AMIS-30623

LIN Micro-Stepping Motor Driver

1.0 General Description

The AMIS-30623 is a single-chip micro-stepping motor driver 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 advanced motion qualification mode enables verification of the complete mechanical system in function of the

selected motion parameters. 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 sensorless 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.
