Working Principles

The MAX6388XS45D4-T operates by comparing the power supply voltage with a set 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 again, providing a debounced and reliable indication of the power supply status.
