Product Description
AMIS-3062x stepper motordriver family with position controller control/diagnostics interface integrated single chip. family consists products: AMIS-30621 with interface, ready build dedicated mechatronics solutions connected remotely with master. AMIS-30622 with SERIAL interface, ready peripheral device next microcontroller. chip receives high-level positioning instructions through interface subsequently drives motor coils until desired position reached. on-chip position controller configurable (OTP Interface) different motor types, positioning ranges parameters speed, acceleration deceleration. AMIS-3062x acts slave master fetch specific status information like actual position, error flags, etc. from each individual slave node.

Applications Benefits
AMIS-3062x family ideally suited small positioning applications. Target markets include: automotive (headlamp alignment, idle control, cruise), industrial equipment (lighting, fluid control, labeling, process, tables) building automation (HVAC, surveillance, satellite dish positioning). Suitable applications typically have multiple axes require mechatronic solutions with driver chip mounted directly motor. high abstraction level products' command reduces load processor master side. Scaling application towards number axes straight-forward: hardware software designs extended modular way, without severely effecting demands master microcontroller. structure simplifies track-layout and/or wiring architectures. Microstepping operation removes design trade-off between minimal operation speed avoiding risk noise step-loss resonance phenomena. stall-detection feature (optional) offers silent, accurate position-calibrations during referencing allows semi-closed loop operation when approaching mechanical end-stops. these benefits result reduced system-cost timeto-market improved technical performance.
