Working Principles

The MAX6719UTZGD3+T is a voltage monitor IC that compares the input voltage with a user-selectable threshold voltage. When the input voltage falls below the threshold, the reset output becomes active, indicating a power failure or an out-of-range condition. The open-drain output can be connected to a microcontroller or other logic circuitry for system reset or power-on reset.

Detailed Application Field Plans
