The LM5051 Low 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 LM5051 controller provides 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 LM5051 can
connect power supplies ranging from -6V to -100V and can withstand transients up to -100V.
The LM5051 also provides a FET test diagnostic mode which allows the system controller to
test for shorted MOSFETs.
