Working Principles

The MAX6712TEXS+T operates by comparing the voltage at the VDD pin with the user-programmed threshold voltage. When the VDD voltage falls below the threshold, the output pin (OUT) goes low, indicating a voltage fault condition. The threshold voltage can be adjusted using external resistors connected to the IC.
