Order this document by MC3479/D MC3479 Stepper Motor Driver The MC3479 is designed to drive a two phase stepper motor in the bipolar mode. The circuit consists of four input sections, a logic decoding/sequencing section, two driver stages for the motor coils, and an output to indicate the Phase A drive state. Single Supply Operation: 7.2 to 16.5 V STEPPER MOTOR DRIVER SEMICONDUCTOR TECHNICAL DATA <.
