Microstep Drivers Deliver High Performance And Reliability

Promising high performance and reliability, the company’s stepper motor drivers offer selectable excitation modes: full-step to sixteenth-step with 1A or 2A outputs and full-step to eighth-step with a 2.5A output. The microstep drivers also provide a selectable current decay pattern (FAST/SLOW/MIXED decay modes), an internal voltage regulator, control input translator, and DMOS output. The regulator permits operation from a single 36V supply. Instead of parallel control lines, a single clock input is converted by the device’s internal translator into motor drive signals. Additionally, the company’s advanced DMOS (Pch + Nch) output topology eliminates the need for external charge pump components. Pricing starts at $3 each. ROHM SEMICONDUCTOR, San Diego, CA.
