A reverse current detection apparatus determines whether an electrical conduction control to a motor coil of a motor is in a predetermined state based on a timing signal representing a timing at which to conduct a source current or a sink current through the motor coil and a control signal for a half bridge in a power stage, and compares the output voltage of the power stage with a threshold value, so as to detect the presence/absence of a reverse flow of a phase current based on these results. A motor driving apparatus for driving a motor under a PWM control includes a rectification switching section for switching a rectification scheme from one to another based on the reverse current detection apparatus and a detection result thereof.
