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.
