FUNCTION
5V Source
-12V Input
12V Input
Ground
-12V Supply Input. Also provides power to the -12V overcurrent circuitry.
5V CMOS Fault Output; LOW = FAULT. An optional capacitor may be placed from this pin
to ground to provide additional immunity from power supply glitches.
Drive the gates of the 3.3V and 5V MOSFETs. Connect a capacitor to ground to set the
startup ramp. During turn on, this capacitor is charged with a 25PA current source.
HIP1011D UV comparator disabled when this pin is below 9.6V nominal.
12V supply input for IC and 12VO. Both 12VIns to be connected to a single +12V supply.
Connect to the load side of the current sense resistor in series with source of external 3.3V
MOSFET.
Connect to source of 3.3V MOSFET. This connection along with (3VISEN) senses the
voltage drop across the sense resistor.
Connect to source of 5V MOSFET switch. This connection along with (5VISEN) senses the
voltage drop across the sense resistor.
Connect to the load side of the current sense resistor in series with source of external 5V
MOSFET.
Controls all four switches. High to turn switches ON, Low to turn them OFF.
This capacitor is charged with a 25PA current source during startup.
HIP1011D UV comparator disabled when this pin >1.4V nominal.
Switched 12V output. Rated for 0.5A.
supply. This capacitor is charged with 25PA during startup.
Connect a resistor from this pin to ground to set the overcurrent trip point of all eight
switches. All eight overcurrent trips can be programmed by changing the value of this
resistor. The default (6.04k:, 1%) is compatible with the maximum allowable currents as
outlined in the PCI specification.
Connect to common of power supplies.
