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
APPLICATIONS
the reverse direction. The LM5051 can connect
power supplies ranging from -6V to -100V and can

Supplies
withstand transients up to -100V.
The LM5051 also provides a FET test diagnostic
mode which allows the system controller to test for
shorted MOSFETs.
