PCI Hot Plug Controller
The HIP1011 is the PCI Hot Plug voltage bus control IC f or use in modern computer systems that facilitates hot plugging of adapter cards into and out of an active or passive back plane. Along with discrete power MOSFETs and a few passivecomponents, the HIP1011 creates a small and simple yet complete power control solution. F our independent supplies are controlled, +5V, +3.3, +12V, and -12V. The +12V and -12V switches are integrated. F or the +5V and +3.3V supplies, overcurrent protection is provided by sensing the voltage across external current-sense resistors. For the +12V and -12V supplies, overcurrent protection is provided internally . In addition, an on-chip reference is used to monitor the +5V, +3.3V and +12V outputs for undervoltage conditions. The PWRON input controls the state of the switches. During an overcurrent condition on any output, or an undervoltage condition on the +5V, +3.3V or +12V outputs, all MOSFETs are immediately latched-off and a LOW (0V) is asserted on the FLTN output. The FLTNlatchiscleared when the PWRON input is toggled low again. During initial power-up of the main
supply (+12V), the PWRON input is inhibited from
V
CC
turning on the switches, and the latch is held in the Reset state until the V
input is greater than 10V.
CC
User programmability of the overcurrent threshold and turn-on slew rate is provided. A resistor connected to the OCSET pin programs the overcurrent threshold. Capacitors connected to the gate pins set the turn-on rate. Also, a capacitor may be added to the FLTN pin to provide noise immunity.

Pin Descriptions
PIN DESIGNATOR FUNCTION DESCRIPTION
1 M12VIN -12V Input -12V Supply Input. Also provides power to the -12V overcurrent circuitry. 2 FLTN Fault Output 5V CMOS Fault Output; LOW = FAULT. An optional capacitor may be place from this pin to
ground to provide additional immunity from power supply glitches.
3 3V5VG 3.3V/5V Gate Output Drive the gates of the 3.3V and 5V MOSFETs. Connect a capacitor to ground to set the start-
up ramp. During turn on, this capacitor is charged with a 25µA current source. 4 VCC 12V VCC Input Connect to unswitched 12V supply. 5 12VIN 12V Input Switched 12V supply input. 6 3VISEN 3.3V Current Sense Connect to the load side of the current sense resistor in series with source of external 3.3V
MOSFET. 7 3VS 3.3V Source Connect to source of 3.3V MOSFET. This connection along with pin 6 (3VISEN) senses the
voltage drop across the sense resistor. 8 OCSET Overcurrent Set Connect a resistor from this pin to ground to set the overcurrent trip point of all four switches. All
four over current trips can be programmed by changing the value of this resistor. The default
(6.04kΩ, 1%) is compatible with the maximum allowable currents as outlined in the PCI specifi-
cation. 9 PWRON Power On Control Controls all four switches. High to Turn Switches ON, Low to turn them OFF.
10 5VS 5V Source Connect to source of 5V MOSFET switch. This connection along with pin 11(5VISEN) senses
the voltage drop across the sense resistor.

Output
Connect a capacitor between 12VG and 12VO to set the start up ramp for the +12V supply.
This capacitor is charged with a 25µA current source during start -up. The 3.3V and 5V UV
circuitry is enabled after the voltage on 12VG is less than 400mV. Therefore, if the capacitor
on the pin 3 (3V5VG) is more than 25% larger than the capacitor on pin 14 (12VG) a false UV
may be detected during start up.
