Working Principles

The MAX16046CECB+T operates by continuously monitoring the power supply voltage using an internal voltage reference. When the voltage falls below the selected threshold, 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. The manual reset input (MR) allows for an immediate system reset when triggered.
