Working Principles

The MAX6719UTWGD3+T operates by comparing the input voltage with a reference voltage set by the threshold pin. When the input voltage falls below the threshold, the reset output is activated, pulling it low. This active-low signal can be used to trigger various actions, such as resetting a microcontroller or shutting down a system.
