Working Principles

The MIC3809BM is a voltage supervisor IC that monitors the supply voltage and generates a reset signal when it falls below a certain threshold. It operates by comparing the supply voltage with an internal reference voltage. When the supply voltage drops below the selected threshold, the reset output is activated. The reset signal remains active until the supply voltage rises above the threshold or a manual reset input is triggered.
