General Description

The LTC®4236 offers ideal diode-OR and Hot Swap functions for two power rails by controlling external N-channel 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.
