AMIS-30623
Micro-stepping Motor Driver
INTRODUCTION
The AMIS30623 is a singlechip microstepping motordriver with
position controller and control/diagnostic interface. It is ready to build
dedicated mechatronics solutions connected remotely with a LIN master.
The chip receives positioning instructions through the bus and
subsequently drives the motor coils to the desired position. The
onchip position controller is configurable (OTP or RAM) for
different motor types, positioning ranges and parameters for speed,
acceleration and deceleration. The AMIS30623 acts as a slave on the
LIN bus and the master can fetch specific status information like
actual position, error flags, etc. from each individual slave node.
An integrated sensorless steploss detection prevents the
positioner from loosing steps and stops the motor when running into
stall. This enables silent, yet accurate position calibrations during a
referencing run and allows semiclosed loop operation when
approaching the mechanical endstops.
The chip is implemented in I2T100 technology, enabling both high
voltage analog circuitry and digital functionality on the same chip.
The AMIS30623 is fully compatible with the automotive voltage
requirements.

AMIS30623
APPLICATIONS
The AMIS30623 is ideally suited for small positioning
applications. Target markets include: automotive (headlamp
alignment, HVAC, idle control, cruise control), industrial
equipment (lighting, fluid control, labeling, process control,
XYZ tables, robots...) and building automation (HVAC,
surveillance, satellite dish, renewable energy systems).
Suitable applications typically have multiple axes or require
mechatronics solutions with the driver chip mounted
directly on the motor.
