Dual Slot PCI Hot Plug Controllers

The HIP1011D, HIP1011E are the first ICs 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. Like the single slot HIP1011B, the

HIP1011E does not monitor output voltage nor respond to

undervoltage conditions.

The HIP1011D, HIP1011E are designed to be physically

placed in close proximity to two adjacent PCI slots thus

reducing layout complexity and placement costs in

assembly. The HIP1011D, HIP1011E provides independent

power control to each slot and the addition of discrete power

MOSFETs and a few passive components creates two

complete power control solutions. The IC integrates the

+12V and -12V current sensing switches for each slot.

Overcurrent (OC) 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 (UV) conditions *. The two

PWRON inputs control the state of the switches, one each

for slot A and slot B outputs. 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 associated FLTN output

and all associated switches are latched-off. The outputs

servicing the adjacent slot are unaffected.

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,

HIP1011E 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.

* UV references do not apply to HIP1011E.
