Working Principles

The MAX16083XR14B+T operates by continuously monitoring the voltage level of the connected power supply. When the voltage falls below the selected threshold voltage, the IC generates a reset signal on the RESET# pin. The reset signal remains active until the voltage rises above the threshold and the reset timeout period elapses.
