UC3717 Datasheet (Unitrode) - Stepper Motor Drive Circuit

UC3717, Stepper Motor Drive Circuit

The UC3717 has been designed to control and drive the current in one winding of a bipolar stepper motor.

The circuit consists of an LSTTL-compatible logic input, a current sensor, a monostable and an output stage with built-in protection diodes.

Two UC3717s and a few external components form a compl
