Abstract
A motor control circuit for forward/reverse rotation comprises a driving circuit, a switching circuit and a motor coil winding. The driving circuit has a driving source, a Hall IC and a driving IC. The driving source provides a signal to enable the Hall IC to output a control signal to the driving IC and the driving IC generates a driving signal after receiving the control signal. The switching circuit is applied for changing the transmitting direction of the control signal or the driving signal. The motor coil winding receives the driving signal and decides motor rotating direction according to the driving signal.
