TEF3718 Datasheet (ST Microelectronics)

TEF3718, STEPPER MOTOR DRIVER

The TEF3718 and TEF3718S are bipolar monolithic integrated circuits intended to control and drive the current in one widing of a bipolar stepper motor.

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