Abstract: A driver device includes a control circuit for controlling an output stage circuit for supplying an output current to a coil, and makes a movable part move with the magnetism generated by the supplied output current. The control circuit can perform holding control to hold the state of the movable part unchanged by suspending its movement. During the holding control by the control circuit, application of an external force tending to change the state of the movable part against the holding control is detected based on the state of supply of electric power to the coil by the output stage circuit, the output current, or the current flowing through the output stage circuit.

Abstract: A driving circuit drives a stepping motor in synchronization with an input clock using a 2-phase excitation method. A constant current chopper circuit generates a pulse modulation signal such that the detection value of the coil current approaches a current setting value. A detection window generation circuit generates a detection window. The detection window becomes an open state at a timing at which the coil current IOUT becomes smaller than a predetermined threshold value. A logic circuit sets a full-bridge circuit to a high-impedance state when the detection window is in the open state and controls the full-bridge circuit according to the pulse modulation signal when the detection window is in the closed state. In the open state of the detection window, a back electromotive force (BEMF) detection circuit detects the BEMF of the coil. A current value setting circuit controls a current setting value based on the BEMF.
