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

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.
