HIP1012A Dual Power Distribution Controller NOc1NTo-8nOR8taE8Rc-CEItNOCoTMOuErMMRTMESeNIcELhDNonEDriDcEwaDFlwOSRwRuE.ipPnNpLtEeoArWrsCt iCElD.ceMEonSEmtIeNG/rTtNsacSt DATASHEET FN4419 Rev 6.00 March 2004 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. Overcurrent protection is facilitated by two external current sense resistors.
