Low Cost Dual Power Distribution Controller
DATASHEET
FN4516 Rev 3.00 August 2004
The HIP1013 is a low cost 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 10A 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.
Over current protection is facilitated by two external current sense resistors.
