Description for the LM5050-1

The LM5050-1/-Q1 High Side OR-ing FET Controller operates inconjunction with an external MOSFET as an ideal diode rectifier when connected in series with apower source. This ORing controller allows MOSFETs to replace diode rectifiers in powerdistribution networks thus reducing both power loss and voltage drops.

The LM5050-1/-Q1 controller provides charge pump gate drive for an external N-ChannelMOSFET and a fast response comparator to turn off the FET when current flows in the reversedirection. The LM5050-1/-Q1 can connect power supplies ranging from 5 V to 75 V and can withstandtransients up to 100 V.
