The LM5050MK-2/NOPB is a high side OR-ing FET Controller operates in conjunction with an external MOSFET as an ideal diode rectifier when connected in series with a power source. This OR-ing controller allows MOSFETs to replace diode rectifiers in power distribution networks thus reducing both power loss and voltage drops. The LM5050-2 controller provides charge pump gate drive for an external N-channel MOSFET and a fast response comparator to turn off the FET when current flows in the reverse direction. The controller can connect power supplies ranging from +6 to +75V and can withstand transients up to +100V. This controller also provides a FET test diagnostic mode which allows the system controller to test for shorted MOSFETs.
