Programmable Systems Outcome 3 Stepper Motor Driver IC + 12V
The use of four output pins to drive a stepper motor can be an inefficient way to use the microcontroller input/output pins. A dedicated integrated circuit, called the SAA1027 stepper motor driver, has been designed to overcome this problem by building the logic step generator, and the transistor switches, into one package.
