An inductive load driven by power MOSFETs, such as in a low voltage motor drive,
using synchronous rectification to reduce the voltage drop across a body diode
of a power MOSFET. A comparative feed back circuit measures voltage across the
power MOSFET to determine when the body diode is conducting, and turns the MOSFET
ON during conductive cycles, and OFF to block reverse current. The obtained synchronous
rectification function is highly sensitive to current flow, while using a very
small number of parts in a configuration that has less complexity.
