1
The device switches from undervoltage reset to normal operation when 1.5 V < V
CC
< 2.5 V.
2
The device monitors V
CC
through an internal factory trimmed voltage divider, which programs the nominal reset threshold. Factory trimmed reset thresholds are
available in approximately 100 mV increments from 2.5 V to 5 V.

1
RESET
Active Low Reset Output. Asserted whenever V
CC
is below the reset threshold, V
TH
. This pin is a push-pull
output stage for the ADM8323 and an open-drain output stage for the ADM8324.
2 GND Ground.
3
MR
Manual Reset Input. This is an active low input that, when forced low for greater than the glitch filter time,
generates a reset. It features a 75 kΩ internal pull-up resistor.
4 WDI Watchdog Input. Generates a reset if the WDI pulse is not within the watchdog window.
5 V
CC
Power Supply Voltage Being Monitored.
