A motor driving apparatus which includes a pair of field-effect transistors connected in series between a first supply voltage and a second supply voltage lower than the first supply voltage, an output smoothing circuit connected to a node between the two field-effect transistors, a driver for controlling on/off states of the field-effect transistors according to an input signal, and a detector for detecting on/off states of body diodes attached respectively to the field-effect transistors. Only after either of the body diodes is detected being on are the field-effect transistors respectively turned on to produce an output corresponding to the input signal so as to eventually produce a desired output voltage from the first supply voltage.
