テツピングモータ駆動回路。 In a stepping motor drive circuit that performs motor phase switching control based on an excitation switching signal and performs chopper control of this motor phase, after the motor phase is switched by the excitation switching signal, the inductance specific to that motor phase reaches a substantially saturated state. A stepping motor drive circuit comprising chopper control cancel means for canceling chopper control of the motor phase.
