Working Principles

The MAX825TEUK+TG05 is a voltage supervisor IC that continuously monitors the power supply voltage. When the voltage falls below the set threshold, it generates a reset signal to ensure proper system operation. The reset signal remains active until the voltage rises above the threshold or a manual reset input is triggered.
