ISL6160 Description and Operation
The ISL6160 is the first power supply sequencer for the
emerging InfiniBand module (IM) hot swap application. This IC
controls both the +12V VB(ulk) and +5V VA(ux) supplies
providing soft start during hot insertion and overcurrent (OC)
protection during operation.
For VB control and protection, the ISL6160 features include an
accurate current detecting comparator, current limiting for the
range of both 25W and 50W capable power ports, a current
regulated time delay to latch off and soft start turn-on ramp.
These features are all programmable with a minimum of
external passive components. The ISL6160 also includes
severe overcurrent protection that immediately shuts down the
MOSFET switch should there be a shorted IM load.
The VB_ON pin provides on-off control of the external VB
switch once VB_IN > 9V. Driving this pin high causes the gate
pin to charge the external gate capacitor with a 10uA current
setting the soft start ramp rate. Large capacitive loads can thus
be safely turned on with no inrush current spiking nor disruption
of the voltage supply rail.
The VB load current passes through an external current sense
resistor. When the voltage across the sense resistor exceeds
the user programmed ISET voltage threshold, the controller
enters current regulation (CR). The regulated current level is
fixed by the R
ISET
and R
SENSE
resistors. See Table 1 for
R
ISET
programming resistor value and the resulting nominal
CR threshold voltage.
During CR, the CTIM pin starts charging the time-out capacitor
with a 20
μ
A current source and the controller enters the delay
time to latch-off period. This feature allows transient currents
that exceed the designed limit to pass without immediately
