ISL9214 (R) Data Sheet November 30, 2006 FN9271.1 Li-ion/Li-Polymer Battery Charger Accepting Two Power Sources Features The ISL9214 is a fully integrated low-cost single-cell Li-ion or Li-polymer battery charger. The charger accepts two power inputs, normally one from a USB (Universal Serial Bus) port and the other from a desktop cradle. The ISL9214 is an ideal charger for smart handheld devices that need to communicate with a personal computer via USB. * Dual Input Power Sources for Cradle and USB * Complete Charger for Single-Cell Li-ion/Polymer Batteries The ISL9214 features 28V maximum voltages for both the cradle and the USB inputs. Due to the 28V rated inputs, lowcost, large output tolerance adapters can be used safely. When both inputs are powered, the cradle input is used to charge the battery. The charge current is programmable for the cradle input with a small resistor. The end-of-charge current is also programmable by another external resistor. The charger incorporates ThermaguardTM which protects the IC against over temperature. If the die temperature rises above a typical value of +125C, a thermal foldback function reduces the charge current automatically to prevent further temperature rise. The charger has two indication pins. The PPR (power present) pin outputs an open-drain logic LOW when either the cradle or the USB input power is attached. The CHG (charge) pin is also an open-drain output that indicates a logic LOW when the charge current is above a minimum current level. When the charge current is below the preset minimum current, the CHG pin will indicate a logic HIGH signal. This status is latched and will be reset under one of these events: (1) the part is disabled and re-enabled; (2) the selected input source has been removed and reapplied, (3) the USBON turns LOW, or (4) the BAT pin voltage falls below the recharge threshold (~3.9V).

USB INPUT QUIESCENT CURRENT vs INPUT VOLTAGE Functional Pin Description CRDL (Pin 1) IMIN (Pin 6) Cradle input. This pin is usually connected to a cradle power input. The maximum input voltage is 28V. The charge current from this pin is programmable with the ICDL pin up to 1A. When this pin is connected to a power source, no charge current is drawn from the USB pin. A 1F or larger value ceramic capacitor is recommended for decoupling. IMIN is the programmable input for the end-of-charge current. IMIN is calculated by the following equation: 550 I MIN = ---------------R IMIN ( mA ) (EQ. 1) Where RIMIN is in k. IMIN is applicable for both cradle and USB charging. USB (Pin 2) USB input. This pin is usually connected to a USB port power connector. Other sources that are also acceptable. The charge current from the USB pin is fixed at typically 380mA. A 1F or larger value ceramic capacitor is recommended for decoupling. It is also recommended to have a 1 resistor in series with the decoupling capacitor to prevent an over-shoot voltage when a USB cable is plugged in. USBON (Pin 7) The USBON pin is a control input to turn off the USB charge function if desired. Connect to LOW or leave floating to turn off USB charge. GND (Pin 8) System ground. ICDL (Pin 9) PPR (Pin 3) Power presence indication. An open-drain output pin which turns ON when either the USB input voltage or the CRDL input voltage is above its POR level, regardless if the charger is enabled or disabled. Otherwise turns OFF. This pin provides a wake-up signal to a microprocessor when either the cradle or the USB power is connected. The ICDL pin has two functions. The first function is to program the cradle charge current during the constantcurrent mode. The voltage of this pin is 1.22V during the constant-current mode of the cradle charger. The constantcurrent mode current is programmed by the following equations: CHG (Pin 4) 6820 I CDL = ----------------R ICDL Charge indication pin. An open-drain output which turns ON when the charge current is above programmable threshold. Otherwise turns OFF. where RICDL is the resistor in k, connected to the ICDL pin (see the Typical Application). EN (Pin 5) Enable logic input. Connect to LOW or leave floating to enable the charger. 7 ( mA ) (EQ. 2) It is recommended that the charge current be programmed in the range of 100mA to 1000mA. FN9271.1 November 30, 2006 ISL9214 The second function of the ICDL pin is to monitor the actual charge current. The voltage of this pin, VICDL, is proportional to the actual charge current, ICHG. The cradle charge current should be programmed equal or higher than the USB current; otherwise, the ICDL pin voltage will be higher than 1.22V during the constant current mode when the USB charger is working. The charger still works properly but the accuracy of the current monitoring voltage degrades and saturates at approximately 2.1V. The USBON pin is equivalent to a logic LOW when left floating. Typically the P-channel MOSFET for the USB input has an rDS(ON) of 600m at room temperature. With a 380mA charge current, the typical head room is 228mV. Thus, if the input voltage drops to a level that the voltage difference between the USB pin and the BAT pin is less than 228mV, the rDS(ON) becomes a limiting factor of the charge current; and the charger drops out the constant current regulation. Cradle Charge Current BAT (Pin 10) Charger output pin. Connect this pin to the battery pack or the battery cell. A 1F or larger value ceramic capacitor is recommended for decoupling. The charger relies on the battery for stability so a battery should always be connected to the BAT pin. Description The ISL9214 is designed for a single-cell Li-ion or Li-polymer battery charging circuit that accepts both a USB port and a desktop cradle as its power source. While the charge current from the USB input source is fixed at 380mA, the charge current from the cradle input is programmable between 0.1A and 1.0A by the resistor RICDL. Similarly, the end-of-charge current is programmable by connecting a resistor at the IMIN pin. The end-of-charge threshold can be calculated with the equation given on the Functional Pin Description section. The same threshold applies to both the cradle and the USB inputs. The cradle charge current is enabled by the EN pin only, the USBON pin has no control on the cradle charge current. The cradle charge current is programmed with the external resistor connected between the ICDL pin and the GND pin. The current can be calculated with the equation given in the ICDL pin description. The typical rDS(ON) of the P-channel MOSFET for the CRDL input is 600m at room temperature. When the head room between the input and output voltages is small, the actual charge current, similar to the USB case, could be limited by the rDS(ON). On the other hand, if the head room between the input and output voltages is large, the charge current may be limited by the thermal foldback threshold. Floating Charge Voltage The floating voltage during the constant voltage phase is 4.2V. The floating voltage has an 1% accuracy over the ambient temperature range of -40C to +85C. Input Auto Selection Trickle Charge Current When both input sources are present, the charger selects only one power source to charge the battery. When the CRDL input is higher than the POR threshold, CRDL is selected as the power source. Otherwise the USB input is selected. If the CRDL input voltage is below the battery voltage but the USB input voltage is higher than the battery voltage, then the USB input is used to charge the battery. The control circuit always breaks both internal power devices before switching from one power source to the other to avoid a cross conduction of both power MOSFETs. When the battery voltage is below the minimum battery voltage VMIN given in the electrical specification, the charger operates in a trickle/preconditioning mode, where the charge current is typically 18% of the programmed charge current for the cradle input. If power comes from the USB input, the trickle current is approximately 80mA. USB Charge Current When the USB port is selected as the power source, the charge current enabled by the logic input at the USBON pin. When the USBON is driven to logic LOW, the charger is disabled. When the USBON is driven to logic HIGH, the charge current is fixed at a typical value of 380mA. Thus for the USB input, the USBON pin has a similar function as the EN pin. The following table describes the USB charge control by both the USBON pin and EN pin: TABLE 1. USB CHARGE CONTROL EN = LOW EN = HIGH USBON = LOW Disabled Disabled USBON = HIGH Enabled Disabled 8 End-Of-Charge Indication When an EOC condition (charge current falls below IMIN during constant voltage charge) is encountered, the CHG pin internal open-drain MOSFET turns off. The IMIN threshold is programmable by the resistor at the IMIN pin for both cradle and USB inputs. Once the EOC condition is reached, the status is latched and can be reset at one of the following conditions: 1. The part is disabled and re-enabled 2. The selected input source has been removed and reapplied 3. The USBON turns LOW and turns back to HIGH for the USB input 4. The BAT pin voltage falls below the recharge threshold (~3.9V) FN9271.1 November 30, 2006 ISL9214 State Diagram TRICKLE CC CV 4.2V IREF CHARGE VOLTAGE 3.9V CHARGE CURRENT 2.6V IMIN 18 IREF 100 CHG INDICATION TIME FIGURE 11. TYPICAL CHARGE CYCLE The state diagram for the charger functions is shown in Figure 12. The diagram starts with the Power-Off state. When at least one input voltage rises above the POR threshold, the charge resets it self. If both input voltages are above the POR threshold, the charger selects the CRDL input as the power source. Then if the EN pin is at a logic HIGH voltage, the charger stays in disabled state. If the EN pin goes LOW, the fast charge starts. Any time the EN pin turns HIGH, the charger returns to the disabled state. When the EOC condition is reached, the CHG will turn to logic HIGH to indicate a charge complete status but the charge will continue. The EOC condition is then latched until one of the four re-charge conditions is encountered, as shown in Figure 11. Figure 11 shows the typical charge profile including the endof-charge event. Power Presence Indication When either the USB or the cradle input voltage is above the POR threshold, the PPR pin internal open-drain MOSFET turns on indicating the presence of input power. Power-Good Conditions Even if there is a power present, the charger will not deliver any current to the output if the power-good conditions are not met. The following two conditions together define the power-good voltage range: 1. VCDRL or VUSB > VPOR 2. VCDRL or VUSB - VBAT > VOS where VPOR is the power on reset threshold, VOS is the offset voltage for the input and output voltage comparator, All these thresholds have hysteresis, as given in the Electrical Specification table. The charger will not charge the battery if the input voltage does not meet the power-good conditions. Thermal Foldback (ThermaguardTM) The thermal foldback function reduces the charge current when the internal temperature reaches the thermal foldback threshold, which is typically 125C. This protects the charger from excessive thermal stress at high input voltages. Input Bypass Capacitors Due to the inductance of the power leads of the wall adapter or USB source, the input capacitor type must be properly selected to prevent high voltage transient during a hot-plug event. A tantalum capacitors is a good choice for its high ESR, providing damping to the voltage transient. Multi-layer ceramic capacitors, however, have a very low ESR and hence when chosen as input capacitors, a 1- series resistor must be used, as shown in the Typical Applications Section, to provide adequate damping. 9 FN9271.1 November 30, 2006 ISL9214 VCRDL < VPOR VUSB < VPOR PWR OFF Charger: OFF PPR: OFF CHG: OFF VCRDL < VPOR VUSB > VPOR EN=HI VCRDL > VPOR VUSB > VPOR EN=HI VCRDL > VPOR VUSB < VPOR EN=HI POR POR POR USB input selected Charger: OFF PPR: ON CHG: OFF CRDL input selected Charger: OFF PPR: ON CHG: OFF CRDL input selected Charger: OFF PPR: ON CHG: OFF SOURCE SELECTED CHARGER DISABLED Not Enabled Charger: OFF PPR: ON CHG: OFF Anytime EN pin changes to disable Enabled, VBAT<VMIN TRICKLE CHARGE Charger: ON PPR: ON CHG: ON VBAT>VMIN Enabled, VBAT>VMIN FAST CHARGE Charger: ON PPR: ON CHG: ON VBAT > VRCH and ICHG < IMIN CHARGE COMPLETE RECHARGE CONDITION is MET and VBAT> VMIN RECHARGE CONDITION is MET and VBAT< VMIN Charger: ON PPR: ON CHG: OFF FIGURE 12.
