ASM690A/692A and ASM802L/802M and ASM805L  
μP Power Supply Supervisor  
With Battery Backup Switch  
General 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 powerfailure 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:

supply voltage drops below 4.65V and the ASM692A /  
ASM802M generate a reset below 4.40V. 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.

Voltage supply for RAM. 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.

Detailed Description  
Application Information  
Microprocessor Interface  
It is important to initialize a microprocessor to a known  
state in response to specific events that could create  
code execution errors and “lock-up”. 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.  
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  
4.7kΩ resistor between the RESET output and the  
microprocessor reset pin. This is shown in Figure 2.  
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 200ms and is LOW for the ASM690A,  
ASM692A, ASM802 and HIGH for the ASM805L. Figure  
1 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 1.1V, 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 1.1V, a 100kΩ 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).

ASM690A/692A and ASM802L/802M and ASM805L  
Watchdog Input  
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 50ns 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.  
Backup-Battery Switchover  
Table 1. Pin Connections in Battery Backup Mode  
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 2Ω PMOS switch but a  
brown-out or loss of VCC will cause a switchover to VBATT  
by means of a 20Ω 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 3) 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 +0.6V.

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 35μA. When VCC drops more than 1.1V 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 1μA.

Although most batteries that meet the requirements of  
Table 2 are acceptable, lithium batteries are very  
effective backup source due to their high-energy density  
and very low self-discharge rates.  
Battery replacement while Powered  
Batteries can be replaced even when the device is in a  
powered state as long as VCC remains above the reset  
threshold voltage VRT. In the ASM devices, a floating  
VBATT pin will not cause a powersupply switchover as can  
occur in some other supervisory circuits. If VBATT is not  
used, the pin should be grounded.  
Backup Power Sources - SuperCap  
Capacitor storage, with very high values of capacitance,  
can be used as a back-up power source instead of  
batteries. SuperCapare 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 that the capacitor voltage remain  
below the maximum voltages shown in Table 2. Although  
the circuit of Figure 4 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 5 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 5V for  
the ASM692A/802M or within ±10% of 5V for the  
ASM690A/802L/805L to insure that the storage  
capacitordoes not achieve an over voltage state.  
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.

excessive loading on the PFO pin. The calculations for  
the correct values of resistors to set the hysteresis  
Power-Fail Comparator  
thresholds are given in Figure 7. A capacitor can be  
added to offer additional noise rejection by low-pass  
filtering.  
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 1.25V 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 6.  
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 8. In this case a good negative  
supply will hold the PFI pin below 1.25V 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 1.25V and  
the PFO pin will go to logic “1”.  
Power Fail Hysteresis  
A noise margin can be added to the simple monitoring  
circuit of Figure 6 by adding positive feedback from the  
PFO pin. The circuit of Figure 7 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 10kΩ to avoid
