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.
