• Sunroof drive mechanisms
• General automotive linear actuation

Procurement Notes

Verify the specific ordering suffix MW001R2G against the official onsemi datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the LIN interface requirements match the target application's bus topology. Check for RoHS compliance status and material declaration documents prior to final procurement. Ensure the 32-QFNW package footprint matches the PCB layout design guidelines provided in the manufacturer's documentation.

Selection Notes

Select this component when a fully integrated solution with LIN communication is required for bipolar stepper motors in automotive environments. The IGBT technology offers specific switching characteristics suitable for high-voltage automotive loads. Consider the 5.5V to 29V operating range for compatibility with standard automotive electrical systems. The 32-pin QFN package is appropriate for applications requiring compact board space and thermal dissipation through the exposed pad.

Part Context

This part belongs to the NCV70628 series of micro-stepping motor drivers from onsemi. It is categorized under PMIC - Power Management ICs and specifically as a Motor Driver/Controller. The series includes variants like NCV70624 which utilize I2C interfaces, whereas the NCV70628 utilizes the LIN protocol. It is distinct from general-purpose drivers by its automotive qualification and integrated power stage.

Replacement Considerations

Direct substitutes include other NCV70628 variants with different suffixes if pinout and functionality remain identical. Cross-reference with NCV70624 only if the application can accommodate I2C instead of LIN. Verify mechanical dimensions and thermal performance before substituting with non-onsemi components.
