Working Principles

The MAX161ACWI+T operates by continuously monitoring the supply voltage using the TH (Threshold Voltage) pin. When the voltage falls below the set threshold, the RESET output is asserted, indicating a low-voltage condition. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered through the MR pin.

The IC also provides the option to program the reset timeout period using an external capacitor connected to the CT (Capacitor Connection for Reset Timeout) pin. This feature allows customization of the time delay between the voltage rising above the threshold and the deassertion of the reset signal.
