ISL6173 (+3.3V & +2.5V) Figures
ISL6111 (+12V, -12V, +3.3V, +5V)
Figures 52 and 53 show the ISL6111 PCI Hot Plug power
switch controller. This IC provides power control for the four
legacy supplies (+12V, -12V, 3.3V, 5V) to a PCI or PCI-X
slot. The +12V and -12V switches are integrated, while the
higher power 3.3V and 5V lines require external N-channel
FETs.
Refer to Figures 54 and 55. Though on different time scales,
both figures show the same event; Figure 54 shows all four
output voltages ramping up, and Figure 55 gives detailed
information pertaining to a single rail (+3.3V) at startup.
There is a 1Ω resistive load on the +3.3V output.

Refer to Figures 56 and 57. Though on different time scales,
both figures show the same event; Figure 56 shows all four
output approaching GND, and Figure 57 gives detailed
information pertaining to a single rail (+3.3V) at shutdown by
EN. There is a 1Ω resistive load on the +3.3V output.
Both Figures 58 and 59 show the same event, each with a
different set of details. Note that PGOOD goes low as soon
as 3.3VS drops, but FLTLN waits until CR mode has expired.
The nominal time-out period for this device is CTIM x 150kΩ.
Turning on into a direct short, the +3.3V section of the
controller goes immediately into CR mode until CRTIM times
out. The nominal time-out period for this device is CTIM x
150kΩ (see Figure 46).
