PROBLEM TO BE SOLVED: To provide a drive apparatus capable of preventing simultaneous turning-on of an FET independent of characteristics or kind of an element. SOLUTION: An FET drive apparatus 1 comprises a detecting part (CMP1, CMP2, E1, E2, OR2) which detects on/off state of body diodes BD1 and BD2 that accompany FET N1 and N2 connected in series across different two potentials. At the timing of detecting that the body diodes BD1 and BD2 are turned on, either the FET N1 or N2 is shifted to an on state. COPYRIGHT: (C)2004,JPO
