Description

Active Low Reset Output. Asserted whenever VCC is below the reset

threshold, VTH.

Push-Pull Output Stage for the ADM6316/ADM6318/ADM6319.

Open-Drain Output Stage for the ADM6320/ADM6321/ADM6322.

Active High Push-Pull Reset Output.

Ground.

Manual Reset Input. This is an active low input that when forced low for at

least 1 µs, generates a reset. It features a 52 kΩ internal pull-up.

Active High Push-Pull Reset Output.

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.

Manual Reset Input.

Power Supply Voltage Being Monitored.
