HIP1011

PCI Hot Plug Controller

DATASHEET

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, +3.3V, +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

turning on the switches, and the latch is held in the Reset

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.

NOTE: Intersil Pb-free products employ special Pb-free material

sets; molding compounds/die attach materials and 100% matte tin

plate termination finish, which is compatible with both SnPb and

Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed

the Pb-free requirements of IPC/JEDEC J Std-020B.
