A conventional motor driving device needs to have, as a stage preceding a motor driver circuit, a regulator circuit as a means of maintaining the current flowing through a high-efficiency motor with high accuracy. This leads to a higher cost, and also to a larger area on the circuit board used. By contrast, according to the present invention, a motor driving device is provided with a motor and a motor driver circuit for controlling the motor, and the motor driver circuit has a function of limiting the current supplied to the motor below a predetermined limit value.
