*Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those listed in the
operational sections of this specification is not implied. Exposure to absolute
maximum ratings for extended periods of time may affect device reliability.

Function
V
CC
V
BATT
Power Supply Input: +5 V Nominal.
Backup Battery Input. As V
CC
falls below the reset threshold and below V
BATT
by 20 mV, V
BATT
will be switched
to V
OUT
. On power-up as V
CC
rises to 20 mV above V
BATT
, V
OUT
will be switched back to V
CC
.
Output Voltage. When V
CC
is above the reset threshold, V
OUT
is connected to V
CC
through an on chip switch.
When V
CC
is below the reset threshold, the higher of V
CC
or V
BATT
is connected to V
OUT
.
0 V. Ground reference for all signals.
Power Fail Comparator Input. If PFI is less than 1.25 V, the power fail output
PFO
goes low. If unused, PFI
should be connected to V
CC
or GND.
Power Fail Comparator Output. If PFI is less than 1.25 V, the power fail output
PFO
goes low.
Logic Output.
RESET
goes low if
1. V
CC
falls below the Reset Threshold
2. The watchdog timer is not serviced within its timeout period (1.6 seconds)
The reset threshold is typically 4.65 V for the ADM690A/ADM802L/ADM805L and 4.4 V for the ADM692A/
ADM802M/ADM805M.
RESET
remains low for 200 ms after V
CC
returns above the threshold.
RESET
also
goes low for 200 ms if the watchdog timer is enabled but not serviced within its timeout period.
Active high RESET output (ADM805L/M only). This is the inverse of
RESET
. The asserted (high) level is V
CC
or V
BATT
whichever is higher.
Watchdog Input. WDI is a three level input. If WDI remains either high or low for longer than 1.6 s, (RESET)
(RESET) is activated. The timer resets with each transition on the WDI line. The watchdog timer may be
disabled if WDI is left floating or is connected to a high impedance three stated logic output.
