LT LTC4227CUFD-2#TRPBF

热交换控制器，OR 控制器1自动重试，UVLO

Overview

The LTC4227CUFD-2 offers ideal diode-OR and Hot Swap™ functions for two power rails by controlling external Nchannel MOSFETs. MOSFETs acting as ideal diodes replace two high power Schottky diodes and the associated heat sinks, saving power and board area. A Hot Swap control MOSFET allows a board to be safely inserted and removed from a live backplane by limiting inrush current. The supply output is also protected against short-circuit faults with a fast acting current limit and internal timed circuit breaker.

The LTC4227CUFD-2 allows turn-on/off control, and reports fault and power good status for the supply.
