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.

VOUT
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.

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.

PFO
Power−fail output. PFO is active LOW whenever the PFI pin is less than 1.25 V.

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.

−
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.

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.

Application Information
Detailed Description
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.
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).

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.

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.

Although most batteries that meet the requirements of
Table 6 are acceptable, lithium batteries are very effective
backup source due to their high−energy density and very low
self−discharge rates.

ASM692A/ASM802M Reset Threshold = 4.4 V
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 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

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.

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”.
