AMIS-30621 LIN Microstepping Motordriver  
Data Sheet  
General Description  
The AMIS-30621 is a member of a stepper motordriver  
family with position controller and control/diagnostics  
interface integrated in one single chip.  
The chip receives high-level positioning instructions through  
the interface and subsequently drives the motor coils until  
the desired position is reached. The on-chip position  
controller is configurable (OTP and Interface) for different  
motor types, positioning ranges and parameters for speed,  
acceleration, and deceleration.  
The family consists of two products:  
• AMIS-30621 with LIN interface, ready to build dedicated  
mechatronics solutions connected remotely with a LIN  
master.  
• AMIS-30622 with SERIAL interface, ready to act as  
peripheral device next to a microcontroller.  
The AMIS-30621 acts as a slave on the bus and the master  
can fetch specific status information like actual position,  
error flags, etc. from each individual slave node.  
Features

Applications and Benefits  
The AMIS-30621 is ideally suited for small positioning  
applications. Target markets include: automotive (headlamp  
alignment, HVAC, idle control, cruise), industrial equipment  
(lighting, fluid control, labeling, process, XYZ tables) and  
building automation (HVAC, surveillance, satellite dish  
positioning). Suitable applications typically have multiple  
axes or require mechatronic solutions with the driver chip  
mounted directly on the motor.  
demands on the master microcontroller. The bus structure  
simplifies PCB track-layout and/or wiring architectures.  
Microstepping operation removes the design trade-off  
between minimal operation speed and avoiding the risk of  
noise and step-loss due to resonance phenomena. The stall-  
detection feature (optional) offers silent, yet accurate  
position-calibrations during the referencing run and allows  
semi-closed loop operation when approaching the  
mechanical end-stops.  
The high abstraction level of the products’ command set  
reduces the load of the processor on the master side.  
Scaling of the application towards number of axes is  
straight-forward: hardware - and software designs are  
extended in a modular way, without severely effecting the  
All these benefits result in reduced system-cost and time-  
to-market and improved technical performance.
