NCV70514MW003BR2G

Overview

The NCV70514MW003BR2G is a micro-stepping stepper motor driver designed for bipolar stepper motors. It supports step resolutions of 1, 1/2, 1/8, 1/16, and 1/32. The device operates with a supply voltage range of 6V to 29V and provides an output current of 800mA. It utilizes I/O pins and SPI for control. The component is qualified to AEC-Q100 standards for automotive applications and functions within a junction temperature range of -45°C to 145°C.

Feature Summary

• Supports multiple micro-stepping resolutions including full, half, eighth, sixteenth, and thirty-second steps.
• Interfaces via standard I/O pins and Serial Peripheral Interface (SPI).
• Qualified for automotive environments with extended temperature operation capabilities.

Applications

• Automotive systems requiring precise stepper motor control
• Bipolar stepper motor drive circuits
• Micro-stepping motion control applications

Procurement Notes

Verify the specific suffix BR2G against official onsemi documentation to confirm tape-and-reel packaging and exact revision status. Ensure the application environment remains within the specified -45°C to 145°C junction temperature limits. Confirm that the 6V to 29V supply voltage range aligns with the system power design. Validate AEC-Q100 qualification requirements if the deployment mandates automotive grade components.

Selection Notes

Select this component when bipolar stepper motor control with micro-stepping precision is required in automotive or industrial settings. The 800mA output current suits moderate load applications. The 32-VFQFN package offers surface mount convenience. Consider the SPI interface complexity versus simple I/O control needs. Verify thermal management strategies for the exposed pad to maintain junction temperatures within safe operating limits during high-duty cycles.

Part Context

The NCV70514 series belongs to onsemi's portfolio of motor drivers tailored for automotive and general industrial use. This specific variant integrates micro-stepping capabilities directly into the driver IC, reducing external component count compared to discrete solutions. The NCV prefix indicates automotive qualification, distinguishing it from commercial grade counterparts in the same family.

Replacement Considerations

Check for direct cross-reference part numbers in onsemi's current product lineup. Verify pin compatibility and electrical specifications before substituting. Note that older revisions like NCV70514MW003R2G may be discontinued; ensure the replacement maintains identical functional parameters and package dimensions.
