Working Principles

The MAX6861UK21+T operates by continuously monitoring the supply voltage connected to the VCC pin. When the voltage falls below the selected threshold, the RESET pin is driven low, indicating a reset condition. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered through the MR pin. The device ensures reliable voltage monitoring and system initialization.
