PCI Hot Plug Controller
The HIP1011 is the PCI Hot Plug voltage bus control IC for 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 passive components, the HIP1011 creates a small and simple yet complete power control solution. Four independent supplies are controlled, +5V, +3.3, +12V, and -12V. The +12V and -12V switches are integrated. For 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 FLTN latch is cleared when the PWRON input is toggled low again. During initial power-up of the main VCC supply (+12V), the PWRON input is inhibited from turning on the switches, and the latch is held in the Reset state until the VCC input is greater than 10V. 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.

Also provides power to the -12V overcurrent circuitry. 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.
3.3V/5V Gate Output 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 25A current source. 12V VCC Input 12V Input 3.3V Current Sense 3.3V Source Overcurrent Set Connect to unswitched 12V supply. Switched 12V supply input. 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 pin 6 (3VISEN) senses the voltage drop across the sense resistor. 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 (6.04k, 1%) is compatible with the maximum allowable currents as outlined in the PCI specification. Controls all four switches. High to Turn Switches ON, Low to turn them OFF. Connect to source of 5V MOSFET switch. This connection along with pin 11(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.

Switched 12V Output Switched 12V output. Ground Gate of Internal PMOS Connect to common of power supplies. Connect a capacitor between 12VG and 12VO to set the start up ramp for the +12V supply. This capacitor is charged with a 25A 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. Connect a capacitor between M12VG and M12VO to set the start up ramp for the M12V supply. This capacitor is charged with 25A during start up. Switched 12V Output.
