You might have a look at two of our IC's, the EDE1200 unipolar (5 or 6
wire) and EDE1204 BiPolar (4 wire) stepper motor controller IC's. These 18
pin chips contain all logic necessary to control stepper motors, including
full/half step, directional control, shaft free-spin, and even a
self-stepping mode. Each datasheet contains full hookup instructions, and
our Stepper Motor FAQ handles common difficulties in getting steppers
running smoothly. Datasheets and pricing are available in the EDExx Family
section on our web site at http://www.elabinc.com
