Working Principles

The MIC2075-1BMM is a low-side power switch that utilizes an integrated charge pump to drive the gate of an N-channel MOSFET. When the enable (EN) pin is high, the device turns on, allowing current to flow from the input (IN) pin to the output (OUT) pin. The feedback (FB) pin monitors the output voltage and adjusts the gate drive accordingly to maintain a stable output. The power good (PG) pin indicates when the output voltage is within the desired range. The fault (FLT) pin is used to detect overcurrent or thermal shutdown conditions.
