Working Principles

The MAX6385XS31D4-T operates by comparing the input voltage with the threshold voltage set by the user using the TH pin. When the input voltage exceeds the threshold, the digital output (OUT) is pulled low. Conversely, when the input voltage falls below the threshold, the output remains high impedance. This voltage monitoring function enables the device to detect overvoltage or undervoltage conditions accurately.
