Procurement Notes
Verify the specific suffix MW1AR2G against the manufacturer's latest datasheet to confirm pinout and electrical specifications match your design requirements. Ensure the 24-QFNW package dimensions align with your PCB footprint. Confirm AEC-Q101 certification status if automotive compliance is mandatory for your project.
Selection Notes
Select this component when a fully integrated solution for bipolar stepper motors is required without external power transistors. It is suitable for designs needing precise microstepping control via SPI or simple Step/Direction signals. Consider the 1.1A output capability and wide operating voltage range for robust performance in varying load conditions.
Part Context
This part belongs to the NCV70516 series of motor drivers manufactured by onsemi. The NCV prefix indicates automotive-grade qualification. The device is designed to simplify stepper motor control by combining logic and power in a single compact package, reducing board space and component count compared to discrete solutions.
Replacement Considerations
Check for direct substitutes within the NCV70516 family that may offer different packaging or slight parameter variations. Verify compatibility with existing firmware if replacing with a variant supporting different interface protocols.
