ABSTRACT:
A stepping motor driver circuit first and second push-pull circuits having first and second output terminals, respectively, first and second driving circuits for driving the first and second push-pull circuits in opposite phases relative to each other, respectively, and first and second holding circuits for driving the first and second push-pull circuits, respectively, so that the output voltage between the first and second output terminals may be reduced to a predetermined holding voltage when a predetermined load is held. Here, each of the first and second holding circuits includes a constant-current source for setting a predetermined constant current, a constant-voltage source for supplying a predetermined reference voltage to set the holding voltage, and an amplifier circuit of the current feedback type for inputting the reference voltage and operating with the constant current.
