Description

1

RESET

(ADM6822/ADM6823/ADM6824/ADM6825)

Open-Drain Output Stage for the ADM6822.

Push-Pull Output Stage for the ADM6823/ADM6824/ADM6825.

RESET (ADM6821)

Active-High Push-Pull Reset Output.

2

GND

Ground.

3

MR (ADM6821/ADM6822/ADM6823)

Manual Reset Input. This is an active-low input, which, when forced low for at

least 1 μs, generates a reset. It features a 50 kΩ internal pull-up.

RESET (ADM6824/ADM6825)

Active-High Push-Pull Reset Output.

4

WDI

(ADM6821/ADM6822/ADM6823/ADM6824)

Watchdog Input. Generates a reset if the voltage 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.

MR (ADM6825)

Manual Reset Input.

5

Power Supply Voltage Being Monitored.
