ISL6111
Current Regulated PCI Hot Plug Power
Switch Controller
The ISL6111 is designed for use in PCI and PCI-X
applications where active current regulation protection of the
motherboard from an abnormal PCI load card is desired.
With the addition of two discrete power MOSFETs and a few
passive components, the ISL6111 provides power control for
the four legacy supplies (-12V, +12V, +5V, +3.3V) to a PCI or
PCI-X slot. This IC integrates the +12V and -12V current
sensing and regulation switches. On the 25W capable 3.3V
and 5V rails, current regulation (CR) protection is provided
by sensing the voltage across external current-sense
resistors and modulation of the gate voltage bias on the
external N-channel power MOSFETs.
During initial power-up of the +12V bias supply, the ENABLE
(EN), Power Good (PG), fault monitoring and reporting
function functions are inhibited if bias voltage <10V. Once
the FETs are enabled they are soft started into the load thus
eliminating supply rail disturbances.
Upon a failure that quickly causes a load current greater
than the programmed CR level on any voltage supply, the
ISL6111 enters its current regulation (CR) mode, limiting the
load current to the user programmed level for the user
determined period of time. The CR level and duration are set
by a single resistor and capacitor respectively. At the end of
the CR duration all the switches will latch off pulling the
outputs low along with the CRTIM (current regulation timer)
and FLTN (fault not) pins indicating a latch-off due to an over
current (OC) condition. If a severe OC condition should
occur, then the ISL6111 immediately latches off all outputs
and sets the FLTN output low.
During operation, if any of the positive voltages falls below
the minimum PCI specified levels the power good (PG)
output will pull low indicating a non compliant voltage to a
load. PG is an open drain output as is FLTN.
The CRSET pin allows programming of the current
regulation levels to be scaled up or down from the PCI
specified levels via a resistor connected between the
CRSET pin and ground.
All faults and latches are cleared by ENABLE being
deasserted low.

NOTE: Intersil Lead-Free products employ special lead-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which is compatible with both SnPb
and lead-free soldering operations. Intersil Lead-Free products are
MSL classified at lead-free peak reflow temperatures that meet or
exceed the lead-free requirements of IPC/JEDEC J Std-020B.
