Dual Slot PCI-Express Hot Plug Controller
ISL6112
The ISL6112 targets the PCI-Express add-in card hot plug
application. Together with two each of N-Channel and
P-Channel MOSFETs, four current sense resistors, and several
external passive components, the ISL6112 provides a
compliant hot plug power control solution to any combination
of two PCI-Express X1, X4, X8 or X16 slots.
The ISL6112 features the ability to program a maximum
current regulated level for each of the MAIN outputs for a
common programmable duration. With this ability, both fault
isolation protection and imperviousness to electrical transients
(OC and soft-start protection) are provided to each system
supply. For each 12VMAIN supply, the current regulated (CR)
level is set by a resistor value dependent on the size of the
PCI-Express connector (X1, X4/X8 or X16) to be powered. This
resistor is a sub ohm standard value current sense resistor;
one each for each of the 3VMAIN and 12VMAIN supplies. The
voltage across this resistor is compared to a 50mV reference,
providing a nominal CR protection level that would be set
above the maximum specified slot limits. The 3.3V supply can
use a 15m& sense resistor, compared to a 50mV reference, to
provide a nominal regulated current limit of 3.3A to all
connector sizes. A shutdown without a CR duration delay is
invoked if RSENSE voltage is >100mV. VAUX is internally
monitored and controlled to provide nominal limiting to 1A of
load current.
The ISL6112 is System Management Interface (SMI) capable,
with an integrated SMBus link for communication, control,
monitoring, and reporting of IC and slot conditions.
Information such as UV, OC, STATUS, and power level are
available. Additionally, the IC has a minimum of I/O for
implementations where Hot-Plug Hardware Interface (HPI) is
implemented.
