Working Principles

The MAX6722AUTVHD3+T monitors the voltage level of the power supply by comparing it with the selected threshold voltage. When the voltage falls below the threshold, the reset output is activated, indicating a low-voltage condition. The reset signal remains active until the voltage rises above the threshold or a manual reset input is triggered. The adjustable or fixed reset timeout period determines how long the reset signal remains active after the voltage returns to normal.
