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 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 V CC n –50mV and activate in 10μs or are programmed by an external filter capacitor. The fast comparators trip at V CC n –150mV and typically respond in 500ns.Each FB n 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.
