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.

FUNCTION
12V Source
DESCRIPTION
Connect to source of associated external N-Channel MOSFET switch to sense output
voltage.
Connect to the gate of associated N-Channel MOSFET switch. A capacitor from this
node to ground sets the turn-on ramp. At turn-on this capacitor will be charged to
≈
17.4V
by a 10µA current source when in 5V/12V mode of operation, otherwise capacitor will be
charged to
≈
11.4V.
Connect to 12V supply. This can be either connected directly to the +12V rail supplying
the load voltage or to a dedicated V
DD
+12V supply.
PWRON1 and PWRON2 are used to turn-on and reset the chip. Both outputs turn-on
when either pin is driven low. After an over current limit fault, the chip is reset by the rising
edge of a reset signal applied to either PWRON pin. Each input has 100µA pull up
capability which is compatible with 3V and 5V open drain and standard logic. PWRON1
is also used to invoke 3.3V control operation in preference to +12V control. By tying pin
4 to pin 3 the charge pump is disabled and the UV threshold also shifts to
≈
2.8V.
Connect to the gate of the external 5V N-Channel MOSFET. A capacitor from this node
to ground sets the turn-on ramp. At turn-on this capacitor will be charged to
≈
11.4V by a
10µA current source.
Connect to the source side of 5V external N-Channel MOSFET switch to sense output
voltage.
Connect to the load side of the 5V sense resistor to measure the voltage drop across this
resistor between 5VS and 5VISEN pins.
PGOOD is driven by an open drain N-Channel MOSFET. It is pulled low when either
output voltage is not within specification or and OC condition exists.
No Connection.

Current Limit Set Resistor
A resistor connected between this pin and ground determines the current level at which
current limit is activated. This current is determined by the ratio of the R
ILIM
resistor to
the sense resistor (R
SENSE
). The current at current limit onset is equal to
10µA x (R
ILIM
/ R
SENSE
).
Connect to the load side of sense resistor to measure the voltage drop across this
resistor.
Connect a 0.1µF capacitor between this pin and V
DD
(Pin 3).
