Abstract:
Provided is a drive circuit for a two-coil stepper motor, including: a rotor; a stator including first, second, and third stator magnetic-pole portions; a coil A to be magnetically coupled to the first stator magnetic-pole portion and the third stator magnetic-pole portion; a coil B to be magnetically coupled to the second stator magnetic-pole portion and the third stator magnetic-pole portion; a drive pulse generation circuit configured to output a drive pulse; a detection pulse generation circuit configured to output a detection pulse for detecting counter-electromotive currents generated in the coil A and the coil B; and a rotation detection circuit configured to receive a detection signal generated due to the detection pulse as input to determine whether or not the rotor has rotated.

Claim (Index 15):
The drive circuit for a two-coil stepper motor according to  claim 2 , wherein, when a rotation detection period of determining whether or not the rotor has rotated is divided into a first rotation detection period on a front side and a second rotation detection period on a back side,\n the detection pulse generation circuit outputs the second detection pulse in the first rotation detection period, the rotation detection circuit determines whether the second detection signal satisfies a given condition, the detection pulse generation circuit outputs the first detection pulse in the second rotation detection period when the given condition is satisfied, and the rotation detection circuit detects rotation of the rotor based on the first detection signal.
