onsemi AMIS-30621
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.FEATURES
