... Data Sheet Dual Power Distribution Controller The HIP1012 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 current source. Capacitors on each gate (see the Typical Application Diagram), create a programmable ramp (soft turn-on) to control inrush currents ...

... The current at current limit onset is equal SENSE R ). The HIP1012 is limited to a 10k min value (OC Vth = 100mV) resistor whereas SENSE the HIP1012A can accommodate a 5k resistor for a lower OC Vth (50mV). Connect to the load side of sense resistor to measure the voltage drop across this resistor. ...

... HIP1012 turns soft start mode protecting the supply rail from sudden current loading. If either PWRON pin is pulled low the HIP1012 will be in true hot swap mode. Both PWRON pins must be high to turn off the HIP1012 thus isolating the power supply from the load through the external FETs ...

... See block diagram for OC latch off circuit suggestion. The HIP1012 is reset by a rising edge on either PWRON pin and is turned on by either PWRON pin being driven low. The HIP1012 can control either +12V/5V or +3.3V/+5V supplies. ...
