Working Principles

The MAX6863UK16+T is designed to monitor the power supply voltage in electronic systems. It compares the input voltage with a user-selectable threshold voltage. When the input voltage falls below the threshold, the reset output is asserted, indicating a power failure or an unstable voltage condition. The manual reset input allows for immediate system reset when required.
