LTC4228CUFD-1#PBF DescripTion

The LTC®4228 offers ideal diode and Hot Swap™ functionsfor two power rails by controlling two external N-channelMOSFETs in each rail. MOSFETs acting as ideal diodes re-place two high power Schottky diodes and the associatedheat sinks, saving power and board area. Hot Swap controlMOSFETs allow boards to be safely inserted and removedfrom a live backplane by limiting inrush current. The supplyoutput is also protected against short-circuit faults with afast acting current limit and internal timed circuit breaker.The LTC4228 regulates the forward voltage drop acrossthe external MOSFETs and sense resistor to ensure smoothcurrent transfer from one supply to the other withoutoscillation. The ideal diodes turn on quickly to reducethe load voltage droop during supply switch-over. If theinput supply fails or is shorted, a fast turn-off minimizesreverse-current transients.The LTC4228 allows independent on/off control, and reportsfault and power good status for the supply. The LTC4228improves on the LTC4225 by recovering more quickly frominput brownouts to preserve the output voltage.Smooth Supply Switchover
