Working Principles

The MAX816CSA+T operates by continuously monitoring the supply voltage using an internal voltage reference. When the voltage falls below the selected threshold level, the IC generates a reset signal on the RESET pin. This signal remains active until the supply voltage rises above the threshold level and the reset timeout period elapses.
