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.

NOTE: Intersil Pb-free products employ special Pb-free material sets; molding
compounds/die attach materials and 100% matte tin plate termination finish,
which are RoHS compliant and 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-020C.
