PBD3517-1 Stepper Motor Drive Circuit

PBD3517-1 Stepper Motor Drive Circuit

PBD 3517/1 is a bipolar, monolithic, integrated circuit, intended to drive a stepper motor in a unipolar, bilevel way. One PBD 3517/1 and a minimum of external components form a complete control and drive unit for LS-TTL- or microprocessor-controlled stepper motor system for currents up to 500mA. Th.
