TEF3718S - STEPPER MOTOR DRIVER

Download the TEF3718S datasheet PDF. This datasheet also covers the TEF3718 variant, as both devices belong to the same stepper motor driver family and are provided as variant models within a single manufacturer datasheet.

General Description

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.
