ISL6112
FN6456.0
Dual Slot PCI-Express Power Controller
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 so that 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 dependant 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 which would be set above the maximum
specified slot limits. The 3.3V supply can use a 15mΩ 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. The 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, power level etc. are
available. Additionally the IC has a minimum of I/O for
implementations where Hot-Plug Hardware Interface (HPI) is
implemented.
