File Number 4516.2
Low Cost Dual Power Distribution
Controller
Features
• HOT SWAP Dual Power Distribution Control for +5V and
+12V or +5V and +3.3V
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.
• Provides Fault Isolation
• Charge Pump Allows the Use of N-Channel MOSFETs
• Redundant Power On Controls
• Power Good and Over Current Latch Indicators
• Adjustable Turn-On Ramp
• Protection During Turn-On
Applications
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.

Although pin compatible with the HIP1012 device, the
HIP1013 does not offer current regulation during an
OC event.
