Working Principles

The MAX6422XS16+T operates by continuously monitoring the voltage at the RESET pin. It compares this voltage with a preset threshold voltage. If the monitored voltage falls below the threshold, the IC generates an active-low reset signal at the RESET_OUT pin. This reset signal can be used to initiate system resets or perform other necessary actions. The MR pin allows for manual reset functionality, enabling users to override the automatic reset generation.
