HIP1011D
Dual PCI Hot Plug Controller
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.
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.
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.
