HIP1011D
November 1999 File Number 4725.1
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.

HIP1011D
Using the HIP1011DEVAL1 Platform
General and Biasing Information
The HIP1011DEVAL1 platform (Figure 24) comes as a three
part set consisting of 1 mother board emulator and 2 load
cards. This evaluation platform allows a designer to evaluate
and modify the performance and functionality of the
HIP1011D in a simple environment.
Test point numbers (TP#) correspond to the HIP1011D
device (U5) pin numbers thus TP3 and TP12 are PWRON_2
and PWRON_1 respectively. These 2 pins are the HIP1011D
control inputs for each of the 2 integrated but independent
PCI power controllers in the HIP1011D.
On the HIP1011DEVAL1 platform are 4 HUF76132SK8,
(11.5mΩ, 30V, 11.5A) N-Channel power MOSFETs, (Q1-
Q4) these are used as the external switches for the +5V and
+3.3V supplies to the load card connectors, P1 and P2.
Current sensing is facilitated by the four 5mΩ 1W metal strip
resistors (R1-R4), the voltages developed across the sense
resistors are compared to references on board the
HIP1011D.
The HIP1011DEVAL1 platform is powered through the J1 to
J5 connector jacks near the top of the board, see Table 2 for
bias voltage assignments.

After properly biasing the HIP1011D and ensuring there is
an adequate ground return from the HIP1011DEVAL1
platform to the power supplies, (otherwise anomalous and
unpredictable results will occur) signal the PWRON inputs
low then insert the load cards as shown in Figure 15.
Signaling either or both PWRON pins high (>2.4V) will turn
on the appropriate FET switches and apply voltage to the
load cards.

HIP1011D
Evaluating Time Delay to Latch-Off
Provided for delay to latch-off evaluation are 2 locations for
1206 SMD capacitors, C7 and C8. Filling these locations
places a capacitor to ground from each of the HIP1011D
FLTN pins thus tailoring the FLTN signal going low ramp
rate. This provides a delay to the fault signal latch-off
threshold voltage, FLTN Vth. By increasing this time the
HIP1011D delays immediate latch-off of the bus supply
switches, thus ignoring transient OC and UV conditions. See
Table 3 illustrating the time it takes for switch gate turn-off
from the FLTN start of response to an OC or UV condition.
The FLTN response to an OC or UV condition is 110ns. See
Figures 20 through 23 for waveforms.
The intent of any protection device is to isolate the supply
quickly so a faulty card does not drag down a supply. A
longer latch-off delay results in less isolation from a faulty
card to supply.
