Overview
The NCV70627DQ002AR2G, produced by onsemi, is a single-chip micro-stepping motor driver that integrates a position controller and a control/diagnostic interface. This device is designed to build dedicated mechatronics solutions, particularly suited for applications requiring remote control via a LIN master. It receives positioning instructions through the LIN bus and drives the motor coils to the desired position. The on-chip position controller is configurable for different motor types, positioning ranges, and parameters for speed, acceleration, and deceleration.
