POWER LIN2.X STEPPER WITH STALL DETECTION PRODUCTION DATA - DEC 18, 2013 Features General Description For 1 bipolar stepper or up to 3 DC motors This system-in-a-chip IC controls bipolar stepper actua- Motor currents up to 2* 800mA (peak) tors with current-choppered micro-stepping. The IC is Programmable chopper current values controlled by a LIN2.x interface. It s LIN-address can cal- for sinus or customized micro-stepping culated by the auto-addressing feature (called SNPD 5.5 - 20V supply voltage (load dump 42V) in ofcfi ial LIN-specicfi ation).
