HIP1011 Data Sheet August 1999 File Number 4311.7 PCI Hot Plug Controller Features 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. • Controls Distribution of Four Supplies: +5V, +3.3V, +12V, and -12V • Internal MOSFET Switches for +12V and -12V Outputs • Microprocessor Interface for On/Off Control and Fault Reporting • Adjustable Overcurrent Protection for All Supplies • Provides Fault Isolation • Adjustable Turn-On Slew Rate • Minimum Parts Count Solution • No Charge Pump Applications • PCI Hot Plug • CompactPCI Pinout HIP1011 (SOIC) TOP VIEW 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.

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 specification. 9 PWRON Power On Control 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. 11 5VISEN 5V Current Sense Connect to the load side of the current sense resistor in series with source of external 5V MOSFET. 12 12VO 13 GND Ground 14 12VG Gate of Internal PMOS 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. 15 M12VG Gate of Internal NMOS Connect a capacitor between M12VG and M12VO to set the start up ramp for the M12V supply.
