Overview
The NCV70514MW003R2G is a bipolar stepper motor driver manufactured by onsemi, designed for industrial and medical applications. It operates within a supply voltage range of 6V to 29V and supports load voltages from 0V to 5.5V. The device features an SPI interface with step/direction control and offers micro-stepping resolutions ranging from full step to 1/16. Packaged in a 32-QFNW (5x5) format, it is qualified under AEC-Q100 standards and functions reliably across a junction temperature range of -40°C to 145°C.
Feature Summary
- Fully integrated control and power stage for bipolar stepper motors
- SPI interface supporting step and direction command protocols
- Micro-stepping capability with selectable resolution up to 1/16
- Automotive-grade qualification compliant with AEC-Q100 standards
Applications
- Industrial automation systems
- Medical equipment requiring precise motion control
- Stepper motor positioning modules
Procurement Notes
Verify component authenticity through authorized distribution channels due to the discontinued status indicated in public records. Confirm package integrity and moisture sensitivity handling procedures prior to assembly. Cross-reference datasheet revisions to ensure compatibility with current design specifications. Validate AEC-Q100 certification documentation if automotive compliance is required for the final system integration.
Selection Notes
Select this component when a fully integrated solution for bipolar stepper motors is required with SPI-based digital control. It is suitable for designs needing micro-stepping precision up to 1/16 resolution. Ensure the application environment supports the specified operating temperature range and that the 32-QFNW package footprint aligns with the PCB layout constraints.
Part Context
This part belongs to the NCV70514 series of motor drivers from onsemi. The series focuses on providing compact, high-performance solutions for bipolar stepper motor applications. The specific suffix indicates the reel packaging configuration and quality grade, distinguishing it from other variants in the same functional family.
Replacement Considerations
Public records indicate this specific part number is obsolete. Evaluate alternative models within the NCV70514 or NCV70517 series for pin-compatible or functionally equivalent replacements. Verify that any substitute maintains the required SPI interface, voltage ratings, and thermal performance characteristics.
