Description
Active-Low Reset Output. Asserted whenever V
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 which, when forced low for at least 1 µs,
generates a reset. It features a 52 k 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 floating to disable the watchdog timer.
Manual Reset Input.
Power Supply Voltage Being Monitored.
