AMIS-30623
Micro-stepping Motor Driver
INTRODUCTION
The AMIS−30623 is a single−chip micro−stepping 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
on−chip position controller is configurable (OTP or RAM) for
different motor types, positioning ranges and parameters for speed,
acceleration and deceleration. The AMIS−30623 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 sensor−less step−loss 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 semi−closed loop operation when
approaching the mechanical end−stops.
The chip is implemented in I2T100 technology, enabling both high
voltage analog circuitry and digital functionality on the same chip.
The AMIS−30623 is fully compatible with the automotive voltage
requirements.
