Description

1

RESET

output stage for the ADM8316 and an open-drain output stage for the ADM8320.

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 logic level on the pin remains low or high for the duration of the

watchdog timeout. The timer is cleared if a logic transition occurs on this pin or if a reset is generated. Leave

this pin floating to disable the watchdog timer.

5

Power Supply Voltage Being Monitored.

Description

1

RESET

output stage for the ADM8318 and an open-drain output stage for the ADM8321.

2

GND

Ground.

3

RESET

Active High Push-Pull Reset Output.

4

WDI

Watchdog Input. Generates a reset if the logic level on the pin remains low or high for the duration of the

watchdog timeout. The timer is cleared if a logic transition occurs on this pin or if a reset is generated. Leave

this pin floating to disable the watchdog timer.
