Working Principles

The MAX6319LHUK29B+T is a voltage monitor IC that operates by comparing the supply voltage with a set threshold voltage. When the supply voltage drops below the threshold, the RESET pin is asserted, indicating a low-voltage condition. The reset signal remains active until the supply voltage rises above the threshold or a manual reset is triggered through the MR pin.
