Working Principles

The MAX6731UTTD3+T is a voltage monitor IC that compares the input voltage at the TH pin with a programmable threshold voltage. When the input voltage falls below the threshold, the reset output (OUT) becomes active, signaling a low-voltage condition. The open-drain configuration of the reset output allows easy interfacing with microcontrollers or other digital logic circuits.
