Abstract: PURPOSE: A two phase BLDC motor driving device is provided to accurately control a motor by reducing the leakage current in a motor driving device and restricting the impulse. CONSTITUTION: First and second transistors are switched according to first and second voltages having a phase difference of 180 degree. First and second switching sections are coupled to the first and second transistors to be switched, and supply the current to coils of a motor. Third and fourth transistors are coupled to the first and second transistors to be switched, and receive the current from the coils. First and second leakage current restricting section disperse the leakage current generated in the first and second transistors, when the first to fourth transistors are turned off.
