Motor drive circuit

Abstract

A motor drive circuit includes: a first H-bridge circuit including a first source transistor and a first sink transistor connected in series and a second source transistor and a second sink transistor connected in series; a second H-bridge circuit including a third source transistor and a third sink transistor connected in series and a fourth source transistor and a fourth sink transistor connected in series; and a first control circuit to turn on or off the first and second source transistors and the third and fourth sink transistors in a synchronized manner, turn on or off the third and fourth source transistors and the first and second sink transistors in a synchronized manner, and further turn on or off the first and second source transistors and the third and fourth sink transistors in a complementary manner to the third and fourth source transistors and the first and second sink transistors.
