The HIP1012A is a HOT SWAP dual supply power distribution controller. Two external N-Channel MOSFETs are driven to distribute power while providing load fault isolation.

At turn-on, the gate of each external N-Channel MOSFET is charged with a 10A current source. Capacitors on each gate (see the Typical Application Diagram), create a programmable ramp (soft turn-on) to control inrush currents. A built in charge pump supplies the gate drive for the 12V supply N-Channel MOSFET switch.
