Контроллер горячей замены1Автоматический повтор, тепловой предел, UVLO

Overview

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.

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.
