- Precision positioning stages
Procurement Notes
Verify the specific suffix AR2G against official onsemi documentation to confirm reel packaging and tape-and-reel specifications. Ensure the part number matches the exact marking code required for your assembly process. Cross-reference the datasheet revision date to confirm compatibility with your design requirements. Confirm RoHS compliance status through the manufacturer's official product status page.
Selection Notes
Select this component when a compact solution for bipolar stepper motor driving is required in automotive or industrial environments. Consider the 32-QFN package for space-constrained designs. Evaluate the 6 V to 29 V operating range against your system power supply. Verify that the integrated protection features meet your safety standards without additional circuitry.
Part Context
This part belongs to onsemi's NCV70514 family of bipolar stepper motor drivers. The NCV prefix indicates automotive-grade qualification, including AEC-Q100 certification. The MW007 variant specifies the particular pinout and internal configuration within the series. This family is designed to replace discrete driver solutions with an integrated IC approach.
Replacement Considerations
Check onsemi's official replacement list for direct substitutes. Verify pin-to-pin compatibility if replacing from other manufacturers. Ensure voltage and current ratings match or exceed original requirements. Confirm package dimensions and thermal characteristics are identical for PCB reuse.
