Working Principles

The MAX708SESA+TG035 is designed to monitor the power supply voltage of a microprocessor. It compares the supply voltage with a user-selectable threshold voltage. If the supply voltage falls below the threshold, the IC generates an active-low reset signal. The reset signal remains active until the supply voltage rises above the threshold or a manual reset input is triggered.
