SAA1027, STEPPER MOTOR DRIVER

SAA1027 II II STEPPER MOTOR DRIVE CIRCUIT The SAA1027 is intended for driving a four phase two stator stepper motor.

The circuit consists of four output stage's, a logic part and three input stages.

The logic part is driven by three input stages; a trigger input stage, an input stage which can change the switching sequence of the logic part so that the motor can rotate clock wise (CW) or counter clock wise (CCW) and a set input stage to set the four output stages.

The three inputs are compatib
