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 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.
