HIP1013

Low Cost Dual Power Distribution

Controller

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 10

µA 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.
