Dual PCI Hot Plug Controller

Features

The HIP1011D is the ﬁrst IC available for independent

control of two PCI Hot Plug slots. The HIP1011D has all the

features and functionality of two single PCI Hot Plug slot

controllers such as the HIP1011A but in the same foot print

area.

• Independent Power Control of 2 PCI Slots

• Turn-Off Delay Time Adjustability

• Internal MOSFET Switches for +12V and -12V Outputs

• µP Interface for On/Off Control and Fault Reporting

• Adjustable Overcurrent Protection for All Eight Supplies

• Provides Fault Isolation

The HIP1011D is designed to be physically placed in close

proximity to two adjacent PCI slots servicing each

independently but reducing layout complexity and placement

costs in assembly. It creates two independent power control

solutions with discrete power MOSFETs and a few passive

components. The four supplies +5V, +3.3V, +12V, and -12V

for each slot are independently controlled. There are four

integrated current sensing switches for the +12V and -12V

and for the +5V and +3.3V supplies overcurrent protection is

provided by sensing the voltage across external current-

sense resistors. In addition, on-chip references are used to

monitor the +5V, +3.3V and +12V outputs for undervoltage

conditions. The two PWRON inputs control the state of the

switches, one each for slot A and slot B outputs. During an

overcurrent condition on any output, or an undervoltage

condition on the +5V, +3.3V or +12V outputs, a LOW (0V) is

asserted on the associated FLTN output and all associated

switches are latched-off. The outputs servicing the adjacent

slot are unaffected.

• Adjustable Turn-On Slew Rate

• Minimum Parts Count Solution

• No Charge Pump

• 100ns Response Time to Over Current

Applications

• PCI Hot-Plug

Tape and Reel

The time to FLTN signal going LOW and MOSFET latch off

is user determined by a single capacitor from each FLTN pin

to ground. This added feature enables the HIP1011D to

ignore system noise transients. 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 and turn-

on slew rate is provided. A resistor connected to the OCSET

pin programs the overcurrent threshold for both slots.

Capacitors connected to the gate pins set the turn-on rate.
