Working Principles

The MAX16065ETM+TCDL operates by continuously monitoring the power supply voltage using an internal voltage reference. When the voltage falls below the set threshold, the IC asserts a reset signal to the connected microcontroller or digital system. The reset signal remains active until the voltage rises above the threshold and the programmable timeout period elapses.
