Electronic apparatus including a motor driving device

Abstract

The present invention provides a motor driving device for easily and accurately detecting an abnormal status of a motor. The motor driving device () includes a control circuit () for generating a driver control signal (S); a driving circuit () for generating a motor driving signal (S) according to the driver control signal (S); an initial position detecting circuit () for detecting an initial position of a motor (); and a rotation detecting circuit () for detecting a rotation status of the motor (). Before the motor () starts to rotate normally, the control circuit () repeatedly performs a serial activation processing including detecting an initial position; applying an initial torque and detecting a motor rotation, and when the repetition number reaches a threshold value 'm' (for example, m=5), the motor () is forced stop.
