AMIS-30621
AMIS-30621 is Micro-Stepping Motor Driver manufactured by onsemi.
Micro-Stepping Motor Driver
INTRODUCTION 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.
The chip is implemented in I2T100 technology, enabling both high voltage analog circuitry and digital functionality on the same chip. The AMIS- 30621 is fully patible with the automotive voltage requirements. http://onsemi.
