Working Principles

The MAX803TEXR+T is designed to monitor the power supply voltage of a microprocessor or other digital systems. It compares the supply voltage with a preset threshold voltage. When the supply voltage drops below the threshold, the reset output is activated, indicating a power failure or an unstable voltage condition. The reset signal remains active until the supply voltage rises above the threshold and stabilizes.
