Based on theory of digital signal logic operation, a low power drive controller circuit was designed for 3-phase brushless motor. PWM control wave, forward/reverse voltages and hall positioning signals were calculated to generate six channels of control signals corresponding to changing-phase sequence, to control 3-phase full-bridge drive motor. The drive controller features small quiescent current, large output current, cross conduction protection and insensitivity to useless signals, and it can find applications in 3-phase motor control, servo motor drive and gimbal control.
