The PF3000 provides all the necessary rails to power a complete system including the application processor, memory and peripherals. The PF3000 operates from an input voltage of up to 5.5 V. Output voltage, startup sequence, and other functions are set using integrated one-time-programmable (OTP) memory, thus providing flexibility and reducing external component count. 6.2 Power Generation The buck regulators in the PF3000 provide supply to the processor cores and to other voltage domains, such as I/O and memory. Dynamic voltage scaling is provided to allow controlled supply rail adjustments for the processor cores and other circuitry. The SW1A and SW1B buck regulators can either be used as independent 1.0 A and 1.75 A regulators, or can be combined as a single 2.75 A regulator. The linear regulators in the PF3000 can be used as general purpose regulators to power peripherals and lower power processor rails. The VCC_SD LDO regulator supports the dual voltage requirement by high speed SD card readers. Depending on the system power path configuration, the LDO regulators can be directly supplied from the main input supply or from the switching regulators to power peripherals, such as audio, camera, Bluetooth, and Wireless LAN, etc. A specific VREFDDR voltage reference is included to provide accurate reference voltage for DDR memories. The VSNVS block behaves as an LDO, or as a bypass switch to supply the SNVS/SRTC circuitry on the i.MX processors; VSNVS may be powered from VIN, or from a coin cell. To accommodate applications that are powered by main supplies of voltages higher than 4.5 V and up to 5.5 V, the PF3000 incorporates a front-end LDO regulator using an external pass FET to keep the maximum regulator input voltage of the regulators at 4.5 V. Applications with an input voltage lower than 4.5 V can directly power the regulators without using the front-end LDO. PF3000 shows a summary of the voltage regulators in the PF3000. Table 35.

Note that each application power tree is dependent upon the system's voltage and current requirements, therefore a proper input voltage should be selected for the regulators. PF3000 30 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION 6.3 Functional Description 6.3.1 Control Logic & Interface Signals The PF3000 is fully programmable via the I2C interface. Additional communication is provided by direct logic interfacing including INTB, RESETBMCU, STANDBY, PWRON, and SD_VSEL. Refer to Table 30 for logic levels for these pins. 6.3.1.1 PWRON PWRON is an input signal to the IC that generates a turn-on event. A turn-on event brings the PF3000 out of OFF and Sleep modes and into the ON mode. Refer to Modes of Operation for the various modes (states) of operation of the IC. The PWRON pin can be configured using OTP to detect a level, or an edge using the PWRON_CFG bit. * If PWRON_CFG = 0, the PWRON signal is high and VIN > UVDET, the PMIC turns on; the interrupt and sense bits, PWRONI and PWRONS respectively, is set. * If PWRON_CFG = 1, VIN > UVDET and PWRON transitions from high to low, the PMIC turns on; the interrupt and sense bits, PWRONI and PWRONS respectively, is set. Any regulator enabled in the Sleep mode remains enabled when transitioning from Sleep to ON, i.e., the regulator is not turned off and then on again to match the start-up sequence. When PWRON_CFG = 1, the PWRON input can be a mechanical switch debounced through a programmable debouncer PWRONDBNC[1:0], to avoid a response to a very short key press. The interrupt is generated for both the falling and the rising edge of the PWRON pin. By default, a 31.25 ms interrupt debounce is applied to both falling and rising edges. The falling edge debounce timing can be extended with PWRONDBNC[1:0] as defined in the table below. The interrupt is cleared by software, or when cycling through the OFF mode. Table 36. PWRON Hardware Debounce Bit Settings (53) Bits PWRONDBNC[1:0] State Turn On Debounce (ms) Falling Edge INT Debounce (ms) Rising Edge INT Debounce (ms) 00 0.0 31.25 31.25 01 31.25 31.25 31.25 10 125 125 31.25 11 750 750 31.25 Notes 53. The sense bit, PWRONS, is not debounced and follows the state of the PWRON pin. 6.3.1.2 STANDBY STANDBY is an input signal to the IC. When it is asserted the part enters standby mode and when de-asserted, the part exits standby mode. STANDBY can be configured as active high or active low using the STANDBYINV bit. See Standby Mode for more details. Note: When operating the PMIC at VIN 2.85 V a coin cell must be present to provide VSNVS, or the PMIC does not reliably enter and exit the STANDBY mode. 6.3.1.3 RESETBMCU RESETBMCU is an open-drain, active low output OTP configurable for two modes of operation. In its default mode, it is de-asserted 2.0 ms after the last regulator in the start-up sequence is enabled. In this mode, the signal can be used to bring the processor out of reset (POR), or as an indicator that all supplies have been enabled; it is only asserted during a turn-off event. In the default mode, the RESETBMCU signal is internal timer based and does not monitor the regulators. When configured for its fault mode, RESETBMCU is deasserted after the start-up sequence is completed only if no faults occurred during start-up. At any time, if a fault occurs and persists for 1.8 ms, RESETBMCU is asserted LOW. The PF3000 is turned off if the fault persists for more than 100 ms. The PWRON signal can be used to restart the part, though if the fault persists, the sequence described above is repeated. To enter the fault mode, set bit OTP_PG_EN of register OTP PWRGD EN to "1" during OTP programming. PF3000 Analog Integrated Circuit Device Data Freescale Semiconductor 31 FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION 6.3.1.4 INTB INTB is an open drain, active low output. It is asserted when any fault occurs, provided that the fault interrupt is unmasked. INTB is deasserted after the fault interrupt is cleared by software, which requires writing a "1" to the fault interrupt bit. 6.3.1.5 SD_VSEL SD_VSEL is an input pin that sets the output voltage range of the VCC_SD regulator. When SD_VSEL = HIGH, the VCC_SD regulator operates in the lower output voltage range. When SD_VSEL = LOW, the VCC_SD regulator operates in the higher output voltage range. The SD_VSEL input buffer is powered by the VDDIO supply. When a valid VDDIO voltage is not present, the output of the SD_VSEL buffer defaults to a logic high thus keeping the VCC_SD regulator output in the lower voltage range. 6.3.2 One-time-programmable Memory One-time-programmable memory is used to store key startup parameters and regulators' configuration information. This eliminates the need to set regulator voltage and sequence using external components. The following parameters are programmable in the PF3000. General: I2C slave address, PWRON pin configuration, RESETBMCU configuration Buck regulators: Output voltage, single phase or independent mode configuration for SW1A and SW1B regulators, switching frequency, regulator start-up sequence and timing Boost regulator and LDOs: Output voltage, regulator start-up sequence and timing The PF3000 starts up based on the contents of the TBBOTP registers. During power up, contents of the OTP memory are loaded on to the TBBOTP registers. There is an optional Try-before-buy mode of operation available which bypasses loading of the OTP memory onto the TBBOTP registers. Instead, regulators directly start up based on the current contents of the TBBOTP registers during this mode of operation. This mode is useful when trying to determine a suitable OTP configuration for the system. TBB mode can also be used in lieu of OTP programming provided a microcontroller can initiate the TBB sequence is available in the system. 6.3.2.1 Register Naming Convention Register and bit names for the TBBOTP registers are prefixed with "OTP". This is to differentiate them from "Functional Registers" which are responsible for real-time control of regulator settings. For example, "OTP_SW1A_VOLT" refers to the TBBOTP register associated with the voltage setting for SW1A regulator. "SW1AVOLT" refers to the functional register which is fed into the SW1A regulator block. During power up, contents of the OTP fuses are copied onto the "OTP_SW1A_VOLT" register which is further copied on to the "SW1AVOLT" register. During normal operation, writes to the "OTP_SW1A_VOLT" register has no effect on the output voltage of the SW1A regulator. Writes to the "SW1AVOLT" register do have an effect. 6.3.2.2 Regulator Startup Sequence Programming Each regulator has 3-bits or 4-bits allocated to program its start-up time slot from a turn-on event; therefore, each can be placed from position one to seven or one to fifteen in the start-up sequence as shown in Table 37. When the sequence is code is set to 0, the regulator remains off during the startup sequence. It can be enabled using I2C after the start up sequence is completed. The delay between each position can be programmed to be 0.5 ms or 2.0 ms as shown in Table 38. The start-up sequence terminates at the last programmed regulator. RESETBMCU pin is de-asserted HIGH 2.0 ms after the last utilized startup slot. Table 37.

As a level sensitive input, an active high signal turns on the part and an active low signal turns off the part, or puts it into Sleep mode. As an edge sensitive input, such as when connected to a mechanical switch, a falling edge turns on the part and if the switch is held low for greater than or equal to 4.0 seconds, the part turns off or enters Sleep mode. Table 39. PWRON Configuration PWRON_CFG Mode 0 PWRON pin HIGH = ON PWRON pin LOW = OFF or Sleep mode 1 PWRON pin pulled LOW momentarily = ON PWRON pin LOW for 4.0 seconds = OFF or Sleep mode I2C Address Configuration 6.3.2.4 The I2C device address can be programmed from 0x08 to 0x0F. This allows flexibility to change the I2C address to avoid bus conflicts. Address bit, I2C_SLV_ADDR[3] in OTP_I2C_ADDR register is hard coded to "1" while the lower three LSBs of the I2C address (I2C_SLV_ADDR[2:0]) are programmable as shown in Table 40.

PF3000 Analog Integrated Circuit Device Data Freescale Semiconductor 35 FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION 6.3.3.1 Start-up Timing Diagram The startup timing of the regulators is programmable through OTP and seq_clk_speed. Figure 6 shows the startup timing of the regulators as determined by their OTP sequence. The trimmed 32 kHz clock controls all the start up timing. UVDET VIN tr1 3V td1 is time from VIN > UVDET to VSNVS starting to rise. td1 is typically 5 ms tr1 is time VSNVS takes to go from 1 V to 3 V. Typically it is 650 s. td1 1V VSNVS td2 td2 is user determined delay. Can be zero if PWRON pulled up to VSNVS PWRON td3 is delay of regulator(s) whose OTP sequence is set to 1. With SEQ_CLK_SPEED = 0.5 ms, td3 is typically 2 ms with a minimum of 1 ms and maximum of 3 ms With SEQ_CLK_SPEED = 2 ms, td3 is typically 4.5 ms with a minimum of 2.5 ms and maximum of 6.5 ms td3 Regulator Outputs td4 td4 is controlled by the OTP sequence setting of the regulator(s).

It is typically 2 ms with a minimum of 1.8 ms and maximum of 2.2 ms. td5 RESETBMCU Figure 6. Startup Timing Diagram 6.3.4 16 MHz and 32 kHz Clocks The PF3000 incorporates two clocks: a trimmed 16 MHz RC oscillator and an untrimmed 32 kHz RC oscillator. The 32 kHz untrimmed clock is only used in the following conditions: * VIN < UVDET * All regulators are in SLEEP mode * All regulators are in PFM switching mode A 32 kHz clock, derived from the 16 MHz trimmed clock, is used when accurate timing is needed under the following conditions: * During start-up, VIN > UVDET * PWRON_CFG = 1, for power button debounce timing When the 16 MHz is active in the ON mode, the debounce times are referenced to the 32 kHz derived from the 16 MHz clock. The exceptions are the LOWVINI and PWRONI interrupts, which are referenced to the 32 kHz untrimmed clock. Switching frequency of the switching regulators is derived from the trimmed 16 MHz clock. The 16 MHz clock and hence the switching frequency of the regulators, can be adjusted to improve the noise integrity of the system. By changing the factory trim values of the 16 MHz clock, the user may add an offset as small as 3.0% of the nominal frequency.

PF3000 36 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION 6.3.5 6.3.5.1 Optional Front-end Input LDO Regulator LDO Regulator Description This section describes the optional front-end LDO regulator provided by the PF3000 in order to facilitate the operation with supply voltages higher than 4.5 V and up to 5.5 V. For non-battery operated applications, when the input supply voltage exceeds 4.5 V, the front-end LDO can be activated by populating the external PMOS pass FET MP1 in Figure 7 and connecting the VPWR pin to the main supply. Under this condition, the LDO control block self-starts with a local bandgap reference. When the VIN pin reaches UVDET rising threshold, the reference is switched to the main trimmed bandgap reference to maintain the required VIN accuracy. In applications using an input supply voltage of 4.5 V or lower, the PMOS pass FET should not be populated, VPWR pin should be grounded externally and the VIN pin should be used instead as the main supply input pin. The input pins of the switching regulators should always be connected to the VIN net. The main components of the LDO regulator are an external power P-channel MOSFET and an internal differential error amplifier. One input of the amplifier monitors a fraction of the output voltage at VIN determined by the resistor ratio of R1 and R2 as shown in Figure 7. The second input to the differential amplifier is from a stable bandgap voltage reference. If the output voltage rises too high relative to the reference voltage, the gate voltage of the power FET is changed to maintain a constant output voltage. In order to maintain the power consumption at reasonable levels during PF3000 Standby and Sleep modes, the LDO circuit enters low power mode of operation using an embedded pass FET while the external pass FET is kept off. When the STBY_LOWPOWER_B bit in register LDOGCTL is set the activation of the low power mode during IC Standby mode is disabled; however the LDO low power mode is always activated during the IC Sleep mode. Moreover, during IC Off mode, an even simpler internal circuit is used to further reduce the power consumption. Refer to Modes of Operation for different modes of operation of the IC. VP WR VPWR VR EF LDOG _ MP1 + VIN R1 CVI N R2 VP WR Figure 7. Front-end LDO Block Diagram 6.3.5.2 Undervoltage/Short-circuit and Overvoltage Detection Short-circuit to GND at VIN is detected using an under voltage monitor at VIN that would sense excessive droop on the VIN line and consequently turn off (disable) the external PMOS pass FET. Overvoltage at VPWR is detected if VPWR exceeds the VPWROV threshold (typically 6.0 V). Upon the detection of an overvoltage event an interrupt is generated and bit 2 is set in INTSTAT3 register. The INTB pin is pulled low if the VPWROVM mask bit is cleared. The interrupt is filtered using a 122 s debouncing circuit. The VPWROV interrupt is not asserted if the overvoltage event occurs during start up. The VPWROVS bit can be read using I2C to detect an overvoltage condition.

Use X5R/X7R ceramic capacitors with a voltage rating at least 2 times the nominal voltage. The 100 F capacitance is the total capacitance on the VIN rail including the capacitance at the various regulator inputs. For example, 2 x 22 F capacitors can be used along with 10 F capacitors at all the SWx and LDOx inputs to achieve a total of 100 F capacitance. 6.3.6 Internal Core Voltages All regulators use the main bandgap as the reference. The main bandgap is bypassed with a capacitor at VCOREREF. VCOREDIG is a 1.5 V regulator that powers all the digital logic in the PF3000. VCOREDIG is regulated at 1.28 V in Off and Coin Cell modes. The VCORE supply is used to bias internal analog rails and the OTP fuses. No external DC loading is allowed on VCORE, VCOREDIG, or VCOREREF. VCOREDIG is kept powered as long as there is a valid supply and/or valid coin cell. 6.3.7 VREFDDR Voltage Reference VREFDDR is an internal PMOS half supply voltage follower capable of supplying up to 10 mA. The output voltage is at one half the input voltage. It is typically used as the reference voltage for DDR memories. A filtered resistor divider is utilized to create a low frequency pole. This divider then uses a voltage follower to drive the load. Figure 8.

Regulators SW1A and SW1B regulators can be configured as a single regulator through OTP. Output of the buck regulators during start up is programmable through OTP. Each regulator has associated registers that control its output voltage during On, Standby, and Sleep modes. During start-up, contents of the OTP_SWx_VOLT register is copied onto the SWxVOLT[4:0], SWxSTBY[4:0] and SWxOFF[4:0]. After boot up, contents of the SWxVOLT, SWxSTBY and SWxOFF registers can be set through I2C to set the output voltage during On, Standby, and Sleep modes respectively.

PF3000 Analog Integrated Circuit Device Data Freescale Semiconductor 39 FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION 6.3.8.1 Switching Modes To improve system efficiency the buck regulators can operate in different switching modes. Changing between switching modes can occur by any of the following means: I2C programming, exiting/entering the Standby mode, exiting/entering Sleep mode, and load current variation. Available switching modes for buck regulators are presented in Table 45. Table 46. Switching Mode Description Mode Description OFF The regulator is switched off and the output voltage is discharged using an internal resistor PFM In this mode, the regulator operates in forced PFM mode. The main error amplifier is turned off and a hysteretic comparator is used to regulate output voltage. Use this mode for load currents less than 50 mA. PWM In this mode, the regulator operates in forced PWM mode. APS In this mode, the regulator operates in pulse skipping mode at light loads and switches over to PWM modes for heavier load conditions. This is the default mode in which the regulators power up during a turn-on event. During soft-start of the buck regulators, the controller transitions through the PFM, APS, and PWM switching modes. 3.0 ms after the output voltage reaches regulation, the controller transitions to the selected switching mode. Depending on the particular switching mode selected, additional ripple may be observed on the output voltage rail as the controller transitions between switching modes. The operating mode of the regulator in On and Standby Modes is controlled using the SWxMODE[3:0] bits associated with each regulator. Table 46 summarizes the Buck regulator programmability for Normal and Standby modes. Table 47. Regulator Mode Control SWxMODE[3:0] Normal Mode Standby Mode 0000 Off Off 0001 PWM Off 0010 Reserved Reserved 0011 PFM Off 0100 APS Off 0101 PWM PWM 0110 PWM APS 0111 Reserved Reserved 1000 (default) APS APS 1001 Reserved Reserved 1010 Reserved Reserved 1011 Reserved Reserved 1100 APS PFM 1101 PWM PFM 1110 Reserved Reserved 1111 Reserved Reserved Transitioning between Normal and Standby modes can affect a change in switching modes as well as output voltage. When in Standby mode, the regulator outputs the voltage programmed in its standby voltage register and operates in the mode selected by the SWxMODE[3:0] bits. Upon exiting Standby mode, the regulator returns to its normal switching mode and its output voltage programmed in its voltage register. PF3000 40 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION Any regulators whose SWxOMODE bit is set to "1" enters Sleep mode if a PWRON turn-off event occurs, and any regulator whose SWxOMODE bit is set to "0" is turned off. In Sleep mode, the regulator outputs the voltage programmed in SWxOFF registers and operates in the PFM mode. The regulator exits the Sleep mode when a turn-on event occurs. Any regulator whose SWxOMODE bit is set to "1" remains on and changes to its normal configuration settings when exiting the Sleep state to the ON state. Any regulator whose SWxOMODE bit is set to "0" is powered up with the same delay in the start-up sequence as when powering ON from Off. At this point, the regulator returns to its default ON state output voltage and switch mode settings. When Sleep mode is activated by the SWxOMODE bit, the regulator uses the set point as programmed by SW1xOFF[4:0] for SW1A/B and by SW2OFF[2:0] for SW2, and SW3OFF[3:0] for SW3. 6.3.8.2 Dynamic Voltage Scaling To reduce overall power consumption, processor core voltages can be varied depending on the mode or activity level of the processor. 1. Normal operation: The output voltage is selected by I2C bits SW1x[4:0] for SW1A/B and SW2[2:0] for SW2, and SW3[3:0] for SW3. A voltage transition initiated by I2C is governed by the DVS stepping rates shown in Table 48. 2. Standby Mode: The output voltage can be selected by I2C bits SW1xSTBY[4:0] for SW1A/B and by bits SW2STBY[2:0] for SW2, and SW3STBY[3:0] for SW3. Voltage transitions initiated by a Standby event are governed by the DVS stepping rates shown in Table 48. 3. Sleep Mode: The output voltage can be higher or lower than in normal operation, but is typically selected to be the lowest state retention voltage of a given processor; it is selected by I2C bits SW1xOFF[4:0] for SW1A/B and by bits SW2OFF[2:0] for SW2, and SW3OFF[3:0] for SW3. Voltage transitions initiated by a turn-off event are governed by the DVS stepping rates shown in Table 48. Table 48. DVS Speed Selection for SWx SWxDVSSPEED Function 0 25 mV step each 2.0 s 1 25 mV step each 4.0 s The regulators have a strong sourcing capability and sinking capability in PWM mode, therefore the fastest rising and falling slopes are determined by the regulator in PWM mode. However, if the regulators are programmed in PFM or APS mode during a DVS transition, the falling slope can be influenced by the load. Additionally, as the current capability in PFM mode is reduced, controlled DVS transitions in PFM mode could be affected. Critically timed DVS transitions are best assured with PWM mode operation. Figure 10 shows the general behavior for the regulators when initiated with I2C programming, or standby control. During the DVS period the overcurrent condition on the regulator should be masked. Figure 10. Voltage Stepping with DVS Note: In SW1A independent and SW1AB single phase modes, DVS to and from the 1.8 V and 3.3 V output voltage settings is not allowed. PF3000 Analog Integrated Circuit Device Data Freescale Semiconductor 41 FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION 6.3.8.3 Regulator Phase Clock The SWxPHASE[1:0] bits select the phase of the regulator clock as shown in Table 49. By default, each regulator is initialized at 90 out of phase with respect to each other. For example, SW1x is set to 0 , SW2 is set to 90 , and SW3 is set to 180 by default at power up. Table 49.

Table 51 shows the selectable options for SWxFREQ[1:0]. For each frequency, all phases are available, this allows regulators operating at different frequencies to have different relative switching phases. However, not all combinations are practical. For example, 2.0 MHz, 90 and 4.0 MHz, 180 are the same in terms of phasing. Table 50 shows the optimum phasing when using more than one switching frequency. Table 50.

SW2 output voltage is programmable from 1.500 V to 1.850 V in 50 mV steps if the OTP_SW2_HI bit is low or from 2.500 V to 3.300 V in 150 mV steps if the bit OTP_SW2_HI is set high. During normal operation, output voltage of the SW2 regulator can be changed through I2C only within the range set by the OTP_SW2_HI bit.

SWBST can supply the VUSB regulator for the USB PHY in OTG mode, as well as the VBUS voltage. Note that the parasitic leakage path for a boost regulator causes the SWBSTOUT and SWBSTFB voltage to be a Schottky drop below the input voltage whenever SWBST is disabled. A load switch is recommended on the output path to isolate the output for applications where this is not desired. The switching NMOS transistor is integrated on-chip. Figure 12 shows the block diagram and component connection for the boost regulator.

PF3000 Analog Integrated Circuit Device Data Freescale Semiconductor 47 FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION 6.3.10 LDO Regulators Description This section describes the LDO regulators provided by the PF3000.

Use X5R/X7R ceramic capacitors. 6.3.10.2 Current Limit Protection All the LDO regulators in the PF3000 have current limit protection. In the event of an overload condition, the regulators transitions from a voltage regulator to a current regulator that regulates output current per the current limit threshold. Additionally, if the REGSCPEN bit in Table 124 is set, the LDO is turned off if the current limit event lasts for more than 8.0 ms. The LDO is disabled by resetting its VLDOxEN bit, while at the same time, an interrupt VLDOxFAULTI is generated to flag the fault to the system processor. The VLDOxFAULTI interrupt is maskable through the VLDOxFAULTM mask bit. By default, the REGSCPEN is not set; therefore, at start-up none of the regulators is disabled if an overloaded condition occurs. A fault interrupt, VLDOxFAULTI, is generated in an overload condition regardless of the state of the REGSCPEN bit. PF3000 48 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION 6.3.10.3 LDO Voltage Control Each LDO is fully controlled through its respective VLDOxCTL register. This register enables the user to set the LDO output voltage according toTable 62 for VLDO1 and VLDO2; and uses the voltage set point on Table 63 for VLDO3 and VLDO4. Table 64 lists the voltage set points for the V33 LDO and Table 65 provides the output voltage set points for the VCC_SD LDO based on SD_VSEL control signal. During power-up, contents of the OTP_VLDO_VOLT register is copied to the VLDOxCTL registers. Table 62.

Each regulator has associated I2C bits for this. Table 66 presents a summary of all valid combinations of the control bits on VLDOxCTL register and the expected behavior of the LDO output. Table 66.

STANDBY refers to a Standby event as described earlier. 6.3.11 VSNVS LDO/Switch VSNVS powers the low power, SNVS/RTC domain on the processor. It derives its power from either VIN, or coin cell, and cannot be disabled. When powered by both, VIN takes precedence when above the appropriate comparator threshold. When powered by VIN, VSNVS is an LDO capable of supplying 3.0 V. When powered by coin cell, the VSNVS output tracks the coin cell voltage by means of a switch, whose maximum resistance is 100 . In this case, the VSNVS voltage is simply the coin cell voltage minus the voltage drop across the switch, which is 100 mV at a rated maximum load current of 1000 A. When the coin cell is applied for the very first time, VSNVS outputs 1.0 V. Only when VIN is applied thereafter does VSNVS transition to its default value. Upon subsequent removal of VIN, with the coin cell attached, VSNVS changes configuration from an LDO to a switch, provided certain conditions are met as described in Table 67.

VSNVS External Components Capacitor Value (F) VSNVS 0.47 PF3000 Analog Integrated Circuit Device Data Freescale Semiconductor 51 FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION 6.3.11.3 Coin Cell Battery Backup The LICELL pin provides for a connection of a coin cell backup battery or a "super" capacitor. If the voltage at VIN goes below the VIN threshold (VTL1), contact-bounced, or removed, the coin cell maintained logic is powered by the voltage applied to LICELL. The supply for internal logic and the VSNVS rail switches over to the LICELL pin when VIN goes below VTL1, even in the absence of a voltage at the LICELL pin, resulting in clearing of memory and turning off VSNVS. Applications concerned about this behavior can tie the LICELL pin to any system voltage between 1.8 V and 3.0 V. A 0.47 F capacitor should be placed from LICELL to ground under all circumstances. 6.3.11.4 Coin Cell Charger Control The coin cell charger circuit functions as a current-limited voltage source, resulting in the CC/CV taper characteristic typically used for rechargeable Lithium-Ion batteries. The coin cell charger is enabled via the COINCHEN bit while the coin cell voltage is programmable through the VCOIN[2:0] bits on register COINCTL on Table 70. The coin cell charger voltage is programmable. In the ON state, the charger current is fixed at ICOINHI. In Sleep and Standby modes, the charger current is reduced to a typical 10 A. In the OFF state, coin cell charging is not available as the main battery could be depleted unnecessarily. The coin cell charging is stopped when VIN is below UVDET. Table 70.

To optimize the thermal management and to avoid overheating, the PF3000 provides thermal protection. An internal comparator monitors the die temperature. Interrupts THERM110, THERM120, THERM125, and THERM130 is generated when the respective thresholds specified in Table 73 are crossed in either direction. The temperature range can be determined by reading the THERMxxxS bits in register INTSENSE0. In the event of excessive power dissipation, thermal protection circuitry shuts down the PF3000. This thermal protection acts above the thermal protection threshold listed in Table 73. To avoid any unwanted power downs resulting from internal noise, the protection is debounced for 8.0 ms. This protection should be considered as a fail-safe mechanism and therefore the system should be configured such that this protection is not tripped under normal conditions. Table 73.

Figure 15. State Diagram To complement the state diagram in Figure 15, a description of the states is provided in following sections. Note that VIN must exceed the rising UVDET threshold to allow a power up. Refer to Table 32 for the UVDET thresholds. Additionally, I2C control is not possible in the Coin Cell mode and the interrupt signal, INTB, is only active in Sleep, Standby, and ON states. 6.5.1.1 ON Mode The PF3000 enters the On mode after a turn-on event. RESETBMCU is de-asserted, and pulled high via an external pull-up resistor, in this mode of operation. To enter the On mode, VIN voltage must surpass the rising UVDET threshold and PWRON must be asserted. From the On mode, when the voltage at VIN drops below the undervoltage falling threshold, UVDET, the state machine transitions to the Coin Cell mode. PF3000 54 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION 6.5.1.2 OFF Mode The PF3000 enters the Off mode after a turn-off event. Only VCOREDIG and VSNVS are powered in the mode of operation. To exit the Off mode, a valid turn-on event is required. RESETBMCU is asserted, LOW, in this mode. Turn off events can be achieved using the PWRON pin, thermal protection, as described below. 6.5.1.3 PWRON Pin The PWRON pin is used to power off the PF3000. The PWRON pin can be configured with OTP to power off the PMIC under the following two conditions: 1. PWRON_CFG bit = 0, SWxOMODE bit = 0 and PWRON pin is low. 2. PWRON_CFG bit = 1, SWxOMODE bit = 0, PWRONRSTEN = 1 and PWRON is held low for longer than 4.0 seconds. Alternatively, the system can be configured to restart automatically by setting the RESTARTEN bit. 6.5.1.4 Thermal Protection If the die temperature surpasses a given threshold, the thermal protection circuit powers off the PMIC to avoid damage. A turn-on event does not power on the PMIC while it is in thermal protection. The part remains in Off mode until the die temperature decreases below a given threshold. See Power Dissipation section for more detailed information. 6.5.1.5 Standby Mode * Depending on STANDBY pin configuration, Standby is entered when the STANDBY pin is asserted. This is typically used for low-power mode of operation. * When STANDBY is de-asserted, Standby mode is exited. A product may be designed to go into a Low-power mode after periods of inactivity. The STANDBY pin is provided for board level control of going in and out of such deep sleep modes (DSM). When a product is in DSM, it may be able to reduce the overall platform current by lowering the regulator output voltage, changing the operating mode of the regulators or disabling some regulators. The configuration of the regulators in Standby is pre-programmed through the I2C interface. Note that the STANDBY pin is programmable for Active High or Active Low polarity, and that decoding of a Standby event takes into account the programmed input polarity as shown in Table 74. When the PF3000 is powered up first, regulator settings for the Standby mode are mirrored from the regulator settings for the ON mode. To change the STANDBY pin polarity to Active Low, set the STANDBYINV bit via software first, and then change the regulator settings for Standby mode as required. For simplicity, STANDBY is generally be referred to as active high throughout this document. Table 74. Standby Pin and Polarity Control STANDBY (Pin) (65) STANDBYINV (I2C bit) (66) STANDBY Control (64) 0 0 0 0 1 1 1 0 1 1 1 0 Notes 64. STANDBY = 0: System is not in Standby, STANDBY = 1: System is in Standby 65. The state of the STANDBY pin only has influence in On mode. 66. Bit 6 in Power Control Register (ADDR - 0x1B) Since STANDBY pin activity is driven asynchronously to the system, a finite time is required for the internal logic to qualify and respond to the pin level changes. A programmable delay is provided to hold off the system response to a Standby event. This allows the processor and peripherals some time after a standby instruction has been received to terminate processes to facilitate seamless entering into Standby mode. When enabled (STBYDLY = 01, 10, or 11) per Table 75, STBYDLY delays the Standby initiated response for the entire IC, until the STBYDLY counter expires. An allowance should be made for three additional 32 kHz cycles required to synchronize the Standby event.

Bits [5:4] in Power Control Register (ADDR - 0x1B) 6.5.1.6 Sleep/LPSR Mode * Depending on PWRON pin configuration, Sleep mode is entered when PWRON is de-asserted and SWxOMODE bit is set. * To exit Sleep mode, assert the PWRON pin. In the Sleep mode, the regulator uses the set point as programmed by SW1xOFF[3:0] for SW1A/B and by SWxOFF[2:0] for SW2 and SW3. The activated regulators maintains settings for this mode and voltage until the next turn-on event. Table 76 shows the control bits in Sleep mode. During Sleep mode, interrupts are active and the INTB pin reports any unmasked fault event. If LPSR is activated by requesting VDD_LPSR and VCC_GPIO to stay ON, LDO1 and LDO3 enables in Low-Power mode. Table 76. Regulator Mode Control SWxOMODE Off Operational Mode (Sleep) (68) 0 Off 1 PFM Notes 68. For sleep mode, activated switching regulators, should use the Off mode set point as programmed by SW1xOFF[4:0] for SW1A/B and SW2OFF[2:0] for SW2, and SW3OFF[3:0] for SW3. 6.5.1.7 Coin Cell Mode In the Coin Cell state, the coin cell is the only valid power source to the PMIC. No turn-on event is accepted in the Coin Cell state. Transition to the OFF state requires that VIN surpasses UVDET threshold. RESETBMCU is held low in this mode. If the coin cell is depleted, a complete system reset occurs. At the next application of power and the detection of a Turn-on event, the system re-initializes with all I2C bits including, those that reset on COINPORB are restored to their default states.

Via these registers the resources of the IC can be controlled. The registers also provide status information about how the IC is operating. The SCL and SDA lines should be routed away from noisy signals and planes to minimize noise pick up. To prevent reflections in the SCL and SDA traces from creating false pulses, the rise and fall times of the SCL and SDA signals must be greater than 20 ns. This can be accomplished by reducing the drive strength of the I2C master via software. It is recommended to use a drive strength of 80 or higher to increase the edge times. Alternatively, this can be accomplished by using small capacitors from SCL and SDA to ground. For example, use 5.1 pF capacitors from SCL and SDA to ground for bus pull-up resistors of 4.8 k. 6.6.1 I2C Device ID I2C interface protocol requires a device ID for addressing the target IC on a multi-device bus. The I2C address is set to 0x08. 6.6.2 I2C Operation The I2C mode of the interface is implemented generally following the Fast mode definition which supports up to 400 kbits/s operation (exceptions to the standard are noted to be 7-bit only addressing and no support for General Call addressing.) The IC interface is configured as "Slave". Timing diagrams, electrical specifications, and further details can be found in the I2C specification, which is available for download at: http://www.nxp.com/acrobat_download/literature/9398/39340011.pdf I2C read operations are also performed in byte increments separated by an ACK. Read operations also begin with the MSB and each byte is sent out unless a STOP command or NACK is received prior to completion. PF3000 only supports single-byte I2C transactions for read and write. The host initiates and terminates all communication. The host sends a master command packet after driving the start condition. The device responds to the host if the master command packet contains the corresponding slave address. In the following examples, the device is shown always responding with an ACK to transmissions from the host. If at any time a NACK is received, the host should terminate the current transaction and retry the transaction. PF3000 uses the "repeated start" operation for reads as shown in Figure 35 . Figure 34. Data transfer on the I2C bus Figure 35. Read Operation PF3000 62 Analog Integrated Circuit Device Data Freescale Semiconductor FUNCTIONAL DESCRIPTION AND APPLICATION INFORMATION 6.6.3 Interrupt Handling The system is informed about important events based on interrupts. Unmasked interrupt events are signaled to the processor by driving the INTB pin low. Each interrupt is latched so that even if the interrupt source becomes inactive, the interrupt remains set until cleared. Each interrupt can be cleared by writing a "1" to the appropriate bit in the Interrupt Status register; this causes the INTB pin to go high. If there are multiple interrupt bits set the INTB pin remains low until all are either masked or cleared. If a new interrupt occurs while the processor clears an existing interrupt bit, the INTB pin remains low. Each interrupt can be masked by setting the corresponding mask bit to a 1. As a result, when a masked interrupt bit goes high, the INTB pin does not go low. A masked interrupt can still be read from the Interrupt Status register. This gives the processor the option of polling for status from the IC. The IC powers up with all interrupts masked, so the processor must initially poll the device to determine if any interrupts are active. Alternatively, the processor can unmask the interrupt bits of interest. If a masked interrupt bit was already high, the INTB pin goes low after unmasking. The sense registers contain status and input sense bits so the system processor can poll the current state of interrupt sources. They are read only, and not latched or clearable. Interrupts generated by external events are debounced; therefore, the event needs to be stable throughout the debounce period before an interrupt is generated. Nominal debounce periods for each event are documented in the INT summary Table 78. Due to the asynchronous nature of the debounce timer, the effective debounce time can vary slightly. 6.6.4 Interrupt Bit Summary Table 78 summarizes all interrupt, mask, and sense bits associated with INTB control.

Only the first two pages can be accessed. On each page, registers 0 to 0x7F are referred to as 'functional', and registers 0x80 to 0xFF as 'extended'. On each page, the functional registers are the same, but the extended registers are different. To access registers in Extended Page 1, one must first write 0x01 to the page register at address 0x7F, and to access registers Extended Page 2, one must first write 0x02 to the page register at address 0x7F. To access the Functional Page from one of the extended pages, no write to the page register is necessary. Registers that are missing in the sequence are reserved; reading from them returns a value 0x00, and writing to them has no effect. The contents of all registers are given in the tables defined in this chapter; each table is structure as follows: Name: Name of the bit Bit #: The bit location in the register (7-0) R/W: Read / Write access and control * R is read-only access * R/W is read and write access * RW1C is read and write access with write 1 to clear Reset: Reset signals are color coded based on the following legend. Bits reset by SC and VCOREDIG_PORB Bits reset by PWRON or loaded default or OTP configuration Bits reset by DIGRESETB Bits reset by PORB or RESETBMCU Bits reset by VCOREDIG_PORB Bits reset by POR or OFFB Default: The value after reset, as noted in the Default column of the memory map. * Fixed defaults are explicitly declared as 0 or 1. * "X" corresponds to Read/Write bits that are initialized at start-up, based on the OTP fuse settings or default if VDDOTP = 1.5 V. Bits are subsequently I2C modifiable, when their reset has been released. "X" may also refer to bits that may have other dependencies. For example, some bits may depend on the version of the IC, or a value from an analog block, for instance the sense bits for the interrupts.

In this case, the Front-End LDO regulator is not used : the external MOSFET has to be unpopulated and VPWR pin must be connected to GND . The capacitors on VPWR can be removed and only a 2.2uF capacitor on VIN to ground is necessary in this case . - Unused BUCK and BOOST: Connect input pin SWxIN to VIN with a 0.1 uF bypass capacitor to ground . Leave LX and FB pins floating . - Unused LDO: output can be left floating. Connect input pin to GND if not shared with other LDOs. Figure 36.

Junction to Ambient Thermal Resistance Nomenclature: the JEDEC specification reserves the symbol RJA or JA (Theta-JA) strictly for junction-to-ambient thermal resistance on a 1s test board in natural convection environment. RJMA or JMA (Theta-JMA) is used for both junction-to-ambient on a 2s2p test board in natural convection and for junction-to-ambient with forced convection on both 1s and 2s2p test boards. It is anticipated that the generic name, Theta-JA, continues to be commonly used. The JEDEC standards can be consulted at http://www.jedec.org. 9.2 Estimation of Junction Temperature An estimation of the chip junction temperature TJ can be obtained from the equation: TJ = TA + (RJA x PD) with: TA = Ambient temperature for the package in C RJA = Junction to ambient thermal resistance in C/W PD = Power dissipation in the package in W The junction to ambient thermal resistance is an industry standard value that provides a quick and easy estimation of thermal performance. Unfortunately, there are two values in common usage: the value determined on a single layer board RJA and the value obtained on a four layer board RJMA. Actual application PCBs show a performance close to the simulated four layer board value although this may be somewhat degraded in case of significant power dissipated by other components placed close to the device. At a known board temperature, the junction temperature TJ is estimated using the following equation TJ = TB + (RJB x PD) with TB = Board temperature at the package perimeter in C RJB = Junction to board thermal resistance in C/W PD = Power dissipation in the package in W When the heat loss from the package case to the air can be ignored, acceptable predictions of junction temperature can be made.
