AMIS-30622  
I²C Micro-Stepping Motor Driver  
General description  
The AMIS-30622 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 AMIS-30622 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.  
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  
a
act as peripheral device next to  
microcontroller.

Applications and benefits  
The AMIS-30622 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.  
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 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.  
All these benefits result in reduced system-cost and  
time-to-market and improved technical performance.
