Working Principles

The MAX6384XS23D3+T operates by comparing the power supply voltage with the selected threshold voltage. When the voltage falls below the threshold, the RESET pin is asserted, generating a reset signal. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered through the MR pin. The adjustable reset timeout period ensures that the reset signal is maintained for a sufficient duration to allow proper system initialization.
