HIP1011
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, +3.3V, +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
V
CC
supply (+12V), the PWRON input is inhibited from
turning on the switches, and the latch is held in the Reset
state until the V
CC
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.

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.
