Using the HIP1011DEVAL1 Platform
General and Biasing Information
The HIP1011DEVAL1 platform (Figure 24) comes as a three
part set consisting of 1 motherboard emulator and 2 load
cards. This evaluation platform allows a designer to evaluate
and modify the performance and functionality of the
HIP1011D or HIP1011E in a simple environment.
Test point numbers (TP#) correspond to the HIP1011D/E
device (U5) pin numbers. Thus TP3 and TP12 are
PWRON_2 and PWRON_1 respectively. These 2 pins are
the HIP1011D/E control inputs for each of the 2 integrated
but independent PCI power controllers in the HIP1011D/E.
On the HIP1011DEVAL1 platform are 4 HUF76132SK8,
(11.5m ? , 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.
Evaluating Time Delay to Latch-Off
Provided for delay to latch-off evaluation are 2 locations for
SMD capacitors, C7 and C8. Filling these locations places a
capacitor to ground from each of the HIP1011D/E 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.
Current sensing is facilitated by the four 5m ? 1W metal strip
resistors (R1-R4), the voltages developed across the sense
resistors are compared to references on board the

The HIP1011DEVAL1 platform is powered through the J1 to

bias voltage assignments.)

After properly biasing the HIP1011D/E 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.
