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.
