Working Principles

The ADM8692ARNZ monitors the supply voltage by comparing it with the selected reset threshold voltage. When the supply voltage falls below the threshold, the reset output is activated, signaling a system reset. The reset output remains active until the supply voltage rises above the threshold and the reset timeout period elapses.
