Description
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 10µA 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. When the current through either resistor exceeds the user programmed value the N-Channel MOSFETs are latched off by the HIP1013. The controller is reset by a rising edge on either PWRON pin.
Choosing the voltage selection mode the HIP1013 controls either +12V/5V or +3.3V/+5V supplies.
Although pin compatible with the HIP1012 device, the HIP1013 does not offer current regulation during an OC event.
