HIP1011A
PCI Hot Plug Controller
The HIP1011A is the second PCI Hot Plug Voltage bus
control IC from Intersil. A drop-in alternative to the widely
used HIP1011, the HIP1011A has the same form, fit and
function but additionally features an adjustable latch-off time
of the MOSFET switches and fault reporting.
Like the HIP1011, the HIP1011A creates a small and simple
yet complete power control solution with discrete power
MOSFETs and a few passive components. 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 (OC) protection is
provided by sensing the voltage across external current-
sense resistors. For the +12V and -12V supplies OC
protection is provided internally. In addition, an on-chip
reference is used to monitor the +5V, +3.3V and +12V
outputs for undervoltage (UV) conditions. The PWRON input
controls the state of the switches. During an OC condition on
any output, or a UV condition on the +5V, +3.3V or +12V
outputs, a LOW (0V) is asserted on the FLTN output and all
MOSFETs are latched-off. The time to FLTN signal going
LOW and MOSFET latch-off is determined by a single
capacitor from the FLTN pin to ground. This added feature
allows the system OS to complete housekeeping activities in
preparation for an unplanned shut down of the affected card.
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, fault
reporting response time, latch-off response time and turn-on
slew rate is provided. A resistor connected to the OCSET pin
programs the OC threshold. A capacitor may be added to
the FLTN pin to adjust both the delay time to reporting a fault
and the latch-off of the supplies after an OC or UV event.
Capacitors connected to the gate pins set the turn-on rate. In
addition the HIP1011A has also been enhanced to tolerate
spurious system noise.
