AMIS-30622

I2C Micro-Stepping Motor

Driver

INTRODUCTION

The AMIS−30622 is a single−chip micro−stepping motor driver

with a position controller and control/diagnostic interface. It is ready

to build intelligent peripheral systems where up to 32 drivers can be

connected to one I2C master. This significantly reduces system

complexity.

The chip receives positioning instructions through the bus and

subsequently drives the stator coils so the two−phase stepper motor

moves to the desired position. The on−chip position controller is

configurable (OTP or RAM) for different motor types, positioning

ranges and parameters for speed, acceleration and deceleration.

Micro−stepping allows silent motor operation and increased

positioning resolution. The advanced motion qualification mode

enables verification of the complete mechanical system in function of

the selected motion parameters. The AMIS−30622 can easily be

connected to an I2C bus where the I2C master can fetch specific status

information like actual position, error flags, etc. from each individual

slave node.

The chip is implemented in I2T100 technology, enabling both high

voltage analog circuitry and digital functionality on the same chip.
