ASM690A/692A, ASM802L/802M, ASM805L mP Power Supply Supervisor with Battery Backup Switch Description The ASM690A / ASM692A / ASM802L / ASM802M / ASM805L offers complete single chip solutions for power supply monitoring and control battery functions in microprocessor systems. Each device implements four functions: Reset control, watchdog monitoring, battery-backup switching and power failure monitoring. In addition to microprocessor reset under power-up and power-down conditions, these devices provide battery-backup switching to maintain control in power loss and brown-out situations. Additional monitoring capabilities can provide an early warning of unregulated power supply loss before the voltage regulator drops out. The important features of these four functions are: * 1.6 second watchdog timer to keep microprocessor responsive * 4.40 V or 4.65 V VCC threshold for microprocessor reset at power-up and power-down * SPDT (Single-pole, Double-throw) PMOS switch connects backup power to RAM if VCC fails * 1.25 V threshold detector for power loss or general purpose voltage monitoring These features are pin-compatible with the industry standard power-supply supervisors. Short-circuit and thermal protection have also been added. The ASM690A / ASM802L / ASM805L generate a reset pulse when the supply voltage drops below 4.65 V and the ASM692A / ASM802M generate a reset below 4.40 V. The ASM802L / ASM802M have power-fail accuracy to 2%. The ASM805L is the same as the ASM690A except that RESET is provided instead of RESET.

When VCC is above the reset threshold, VOUT connects to VCC through a P-Channel MOS device. If VCC falls below the reset threshold, this output will be connected to the backup supply at VBATT (or VCC, whichever is higher) through the MOS switch to provide continuous power to the CMOS RAM. 2 2 VCC +5 V power supply input. 3 3 GND Ground. 4 4 PFI Power failure monitor input. PFI is connected to the internal power fail comparator which is referenced to 1.25 V. The power fail output (PFO) is active LOW but remains HIGH if PFI is above 1.25 V. If this feature is unused, the PFI pin should be connected to GND or VOUT. 5 5 PFO Power-fail output. PFO is active LOW whenever the PFI pin is less than 1.25 V. 6 6 WDI Watchdog input. The WDI input monitors microprocessor activity. An internal timer is reset with each transition of the WDI input. If the WDI is held HIGH or LOW for longer than the watchdog timeout period, typically 1.6 seconds, RESET (or RESET) is asserted for the reset pulse width time, tRS, of 140 ms, minimum. 7 - RESET Active-LOW reset output. When triggered by VCC falling below the reset threshold or by watchdog timer timeout, RESET pulses low for the reset pulse width tRS, typically 200 ms. It will remain low if VCC is below the reset threshold (4.65 V in ASM690A / ASM802L and 4.4 V in the ASM692A / ASM802L) and remains low for 200 ms after VCC rises above the reset threshold. - 7 RESET Active-HIGH reset output. The inverse of RESET. 8 8 VBATT Auxiliary power or backup-battery input. VBATT should be connected to GND if the function is not used. The input has about 40 mV of hysteresis to prevent rapid toggling between VCC and VBATT. http://onsemi.com 2 ASM690A/692A, ASM802L/802M, ASM805L Table 2.

The reset output of these supervisory circuits send a reset pulse to the microprocessor in response to power-up, power-down/power-loss or a watchdog time-out. Microprocessor Interface The ASM690 has logic-LOW RESET output while the ASM805 has an inverted logic-HIGH RESET output. Microprocessors with bidirectional reset pins can pose a problem when the supervisory circuit and the microprocessor output pins attempt to go to opposite logic states. The problem can be resolved by placing a 4.7 kW resistor between the RESET output and the microprocessor reset pin. This is shown in Figure 4. Since the series resistor limits drive capabilities, the reset signal to other devices should be buffered. RESET/RESET Timing Power-up reset occurs when a rising VCC reaches the reset threshold, VRT, forcing a reset condition in which the reset output is asserted in the appropriate logic state for the duration of tRS. The reset pulse width, tRS, is typically around 200 ms and is LOW for the ASM690A, ASM692A, ASM802 and HIGH for the ASM805L. Figure 3 shows the reset pin timing. Power-loss or "brown-out" reset occurs when VCC dips below the reset threshold resulting in a reset assertion for the duration of tRS. The reset signal remains asserted as long as VCC is between VRT and 1.1 V, the lowest VCC for which these devices can provide a guaranteed logic-low output. To ensure logic inputs connected to the ASM690A / ASM692A/ASM802 RESET pin are in a known state when VCC is under 1.1 V, a 100 kW pull-down resistor at RESET is needed: the logic-high ASM805L will need a pull-up resistor to VCC. Watchdog Timer A Watchdog time-out reset occurs when a logic "1" or logic "0" is continuously applied to the WDI pin for more than 1.6 seconds. After the duration of the reset interval, the watchdog timer starts a new 1.6 second timing interval; the microprocessor must service the watchdog input by changing states or by floating the WDI pin before this interval is finished. If the WDI pin is held either HIGH or LOW, a reset pulse will be triggered every 1.8 seconds (the 1.6 second timing interval plus the reset pulse width tRS). Figure 3. RESET/RESET Timing Figure 4. Interfacing with Bi-directional Microprocessor Reset Inputs http://onsemi.com 5 ASM690A/692A, ASM802L/802M, ASM805L Watchdog Input Table 5. PIN CONNECTIONS IN BATTERY BACKUP MODE As discussed in the Reset section, the Watchdog input is used to monitor microprocessor activity. It can be used to insure that the microprocessor is in a continually responsive state by requiring that the WDI pin be toggled every second. If the WDI pin is not toggled within the 1.6 second window (minimum tWD + tRS), a reset pulse will be asserted to return the microprocessor to the initial start-up state. Pulses as short as 50 ns can be applied to the WDI pin. If this feature is not used, the WDI pin should be open circuited or the logic placed into a high-impedance state to allow the pin to float. Pin VOUT Connected to VBATT through internal PMOS switch VBATT Connected to VOUT PFI Disabled PFO Logic-LOW RESET Backup-Battery Switchover WDI A power loss can be made less severe if the system RAM contents are preserved. This is achieved in the ASM690/ 692/802/805 by switching from the failed VCC to an alternate power source connected at VBATT when VCC is less than the reset threshold voltage (VCC < VRT), and VCC is less than VBATT. The VOUT pin is normally connected to VCC through a 2 W PMOS switch but a brown-out or loss of VCC will cause a switchover to VBATT by means of a 20 W PMOS switch. Although both conditions (VCC < VRT and VCC < VBATT) must occur for the switchover to VBATT to occur, VOUT will be switched back to VCC when VCC exceeds VRT irrespective of the voltage at VBATT. It should be noted that an internal device diode (D1 in Figure 5) will be forward biased if VBATT exceeds VCC by more than a diode drop when VCC is switched to VOUT. Because of this it is recommended that VBATT be no greater than VRT + 0.6 V. Connection Logic-LOW (except on ASM805 where it is HIGH) Watchdog timer disabled During the backup power mode, the internal circuitry of the supervisory circuit draws power from the battery supply. While VCC is still alive, the comparator circuits remain alive and the current drawn by the device is typically 35 mA. When VCC drops more than 1.1 V below VBATT, the internal switchover comparator, the PFI comparator and WDI comparator will shut off, reducing the quiescent current drawn by the IC to less than 1 mA. Backup Power Sources - Batteries Battery voltage selection is important to insure that the battery does not discharge through the parasitic device diode D1 (see Figure 5) when VCC is less than VBATT and VCC > VRT.

In the ASM devices, a floating VBATT pin will not cause a power supply switchover as can occur in some other supervisory circuits. If VBATT is not used, the pin should be grounded. Backup Power Sources - SuperCapt Capacitor storage, with very high values of capacitance, can be used as a back-up power source instead of batteries. SuperCap are capacitors with capacities in the fractional farad range. A 0.1 farad SuperCap would provide a useful backup power source. Like the battery supply, it is important Figure 5. Internal Device Configuration of Battery Switch-over Function http://onsemi.com 6 ASM690A/692A, ASM802L/802M, ASM805L Power-Fail Comparator that the capacitor voltage remain below the maximum voltages shown in Table 6. Although the circuit of Figure 6 shows the most simple way to connect the SuperCap, this circuit cannot insure that an over voltage condition will not occur since the capacitor will ultimately charge up to VCC. To insure that an over voltage condition does not occur, the circuit of Figure 7 is preferred. In this circuit configuration, the diode-resistor pair clamps the capacitor voltage at one diode drop below VCC. VCC itself should be regulated within 5% of 5 V for the ASM692A/802M or within 10% of 5 V for the ASM690A/802L/805L to insure that the storage capacitor does not achieve an over voltage state. The Power Fail feature is an independent voltage monitoring function that can be used for any number of monitoring activities. The PFI function can provide an early sensing of power supply failure by sensing the voltage of the unregulated DC ahead of the regulated supply sensing seen by the backup-battery switchover circuitry. The PFI pin is compared to a 1.25 V internal reference. If the voltage at the PFI pin is less than this reference voltage, the PFO pin goes low. By sensing the voltage of the raw DC power supply, the microprocessor system can prepare for imminent power-loss, especially if the battery backup supply is not enabled. The input voltage at the PFI pin results from a simple resistor voltage divider as shown in Figure 8. Figure 6. Capacitor as a Backup Power Source Figure 8. Simple Voltage Divider Sets PFI Trip Point Power Fail Hysteresis A noise margin can be added to the simple monitoring circuit of Figure 8 by adding positive feedback from the PFO pin. The circuit of Figure 9 adds this positive "latching" effect by means of an additional resistor R3 connected between PFO and PFI which helps in pulling PFI in the direction of PFO and eliminating an indecision at the trip point. Resistor R3 is normally about 10 times higher in resistance than R2 to keep the hysteresis band reasonable and should be larger than 10 kW to avoid excessive loading on the PFO pin. The calculations for the correct values of resistors to set the hysteresis thresholds are given in Figure 9. A capacitor can be added to offer additional noise rejection by low-pass filtering. Figure 7. Capacitor as a Backup Power Source Voltage Clamped to 0.5 V below VCC Operation without a Backup Power Source When operating without a back-up power source, the VBATT pin should be connected to GND and VOUT should be connected to VCC, since power source switchover will not occur. Connecting VOUT to VCC eliminates the voltage drop due to the ON-resistance of the PMOS switch. http://onsemi.com 7 ASM690A/692A, ASM802L/802M, ASM805L Monitoring Capabilities of the Power-fail Input: Although designed for power supply failure monitoring, the PFI pin can be used for monitoring any voltage condition that can be scaled by means of a resistive divider. An example is the negative power supply monitor configured in Figure 10. In this case a good negative supply will hold the PFI pin below 1.25 V and the PFO pin will be at logic "0". As the negative voltage declines, the voltage at the PFI pin will rise until it exceeds 1.25 V and the PFO pin will go to logic "1". Figure 9. Hysteresis Added to PFI Pin Figure 10.
