Abstract:
A motor driver system includes an excess current sensing device configured to compensate a sensing value depending on a temperature of a motor, and to output the compensated sensing value, the sensing value being obtained from a current value associated with the motor; and a controller configured to stop the motor when the compensated sensing value exceeds a preset excess value.
