Working Principles

The ADM8693ARN is a voltage supervisor integrated circuit that continuously monitors the supply voltage of a microprocessor or digital system. It compares the supply voltage with a preset threshold voltage and generates a reset signal when the supply voltage falls below the threshold. The reset signal remains active until the supply voltage rises above the threshold and a timeout period elapses.

The device also includes a manual reset input, allowing for an immediate system reset when triggered. The reset timeout period can be adjusted by connecting an external capacitor to the CT pin, providing flexibility in meeting specific application requirements.
