Abstract
A data processing apparatus that controls an inverter circuit for a motor. The data processing apparatus including a control unit that monitors a potential of a power supply terminal to supply power to the inverter circuit, and obtains an information indicative of an amount of a driving current flowing in a motor winding of the motor in response to an amount of a current flowing in a resistive element included in the inverter circuit, to control a driving of the motor. The control unit makes the motor winding and the resistive element form a loop circuit, when the potential of the power supply terminal exceeds a predetermined value.
