AMIS-30621: Stepper Motor Driver And Controller With LIN Bus And Micro-stepping Features

The AMIS-30621 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 AMIS-30621 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. 2 The chip is implemented in I T100 technology, enabling both high voltage Analog circuitry and digital functionality on the same chip. The AMIS-30621 is fully compatible with the automotive voltage requirements. By AMI Semiconductor, Inc.
