The LTC®4228 offers ideal diode and Hot Swap™ functions for two power rails by controlling two external N-channel MOSFETs in each rail.

MOSFETs acting as ideal diodes replace two high power Schottky diodes and the associated heat sinks, saving power and board area.

Hot Swap control MOSFETs allow boards to be safely inserted and removed from a live backplane by limiting inrush current.
