The LTC
?/DIV>
4230 is a 3-channel Hot Swap
TM
 controller that
allows a board to be safely inserted and removed from a
live backplane. Internal high side switch drivers control
the gates of external N-channel MOSFETs for supply
voltages ranging from 1.7V to 16.5V. The LTC4230 pro-
vides soft-start and inrush current limiting during the
programmable start-up period.
On-chip current limit comparators provide dual level
circuit breaker protection. The slow comparators trip at
V
CCn
  50mV and activate in 10祍 or are programmed by
an external filter capacitor. The fast comparators trip at
V
CCn
  150mV and typically respond in 500ns.
Each FBn pin monitors its own output supply voltage and
signals its RESET pin. The ON pin turns the chip on and
off and can be used for a reset function. The LTC4230 also
provides additional functions including fault indication,
autoretry or latchoff modes, programmable current limit
response time based on the FAULT and FILTER pins
functionality.
