Product Description

The AMIS-30622 is a stepper motordriver with position

controller and control/diagnostics interface integrated in

one single chip.

The product is ready to be connected as a peripheral

device to a microcontroller with minimal loading of the

microcontroller. The chip receives high level positioning

instructions through the I²C interface and subsequently

drives the motor coils until the desired position is reached.

The on-chip position controller is configurable for different

motor types, positioning ranges and parameters for

speed, acceleration, deceleration, hold current, safe

position. Six OTP bytes are available to set default values,

and can be overruled by values programmed through the

C bus.

The AMIS-30622 acts as a slave on the serial bus and the

master can fetch specific status information like actual

position, error flags, etc. from each individual slave node.

Applications and Benefits

The AMIS-30622 is ideally suited for small positioning

applications. Target markets include automotive, industrial

equipment and building automation. Applications of

interest have typically multiple axes.

The high abstraction level of the product’s 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 affecting the

demands on the master microcontroller. The I

C 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.

All these benefits result in reduced system cost and time-

to-market and improved technical performance.
