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.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J Std-020B.
