Dual Slot PCI-E Hot Plug Controllers
The ISL6113, ISL6114 both target the PCI-Express Add-in card
hot swap application. Together with a pair of N-Channel and
P-Channel MOSFETs, and two sense resistors per slot, either
provides compliant hot plug power control to any combination
of two PCI-Express X1, X4, X8 or X16 slots.
The ISL6113, ISL6114 feature a programmable current
regulated (CR) maximum level for a programmable period to
each voltage load so that both fault isolation protection and
imperviousness to electrical transients are provided.
For each +12V supply, the CR level is set by a resistor value
depending on the needs 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 for each slot and the voltage
across this resistor is compared to a 50mV reference providing
a nominal CR protection level adequately above the specific
slot maximum limits. The 3.3V supply uses a 15mΩ sense
resistor compared to a 50mV reference to provide 3.3A of
maximum regulated current to all connector sizes. The
3.3VAUX is internally monitored and controlled to provide a
nominal maximum of 1A of AUX output current.
The CR period for each slot is set by a separate external
capacitor on the associated CFILTER pin. Once the CR period
has expired, the IC then quickly turns off its associated FETs
thus unloading the faulted card from the supply voltage rails. A
nominal 3.3V must always be present on the AUXI pin for
proper IC bias; this should be the 3.3VAUX supply if used, if not
the AUXI pin is tied directly to the 3VMAIN supply. Both ICs
employ a card presence detection input that disables the MAIN
and AUX enabling inputs if it is not pulled low. Output voltage
monitoring with both PCI-E Reset Not and Power Good Not
reporting along with OC Fault reporting are provided. Whereas
the ISL6113 has the same GATE drive and response
characteristics as the ISL6112, the ISL6114 has a lower turn-on
GATE drive current allowing for the use of smaller
compensation capacitors and thus much faster response to
Way Overcurrent (WOC) conditions. Additionally, the ISL6114
does not turn-on with the CR feature invoked as do the
ISL6112, ISL6113 allowing for shorter CR programmed
periods.The ISL6113, ISL6114 are footprint compatible for all
common pins, but not entirely function compatible with the
ISL6112’s QFN package as there are I/O differences.
