Working Principles

The MAX6804US44D3+T operates by continuously monitoring the supply voltage. When the voltage falls below the selected threshold, the reset output is activated, indicating a power failure or low voltage condition. The reset output remains active until the voltage rises above the threshold or a manual reset signal is applied.
