LTC4238CUFD#PBF Products

The LTC4230CGN is a 3-channel Hot Swap™ 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 LTC4230CGN provides 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 VCCn – 50mV and activate in 10µs or are programmed by an external filter capacitor. The fast comparators trip at VCCn – 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 LTC4230CGN also provides additional functions including fault indication, autoretry or latchoff modes, programmable current limit response time based on the FAULT and FILTER pins’ functionality.
