NCV33033DWR2G

Overview

The NCV33033DWR2G is a Brushless DC (BLDC) motor controller manufactured by onsemi, designed for robust and efficient power control in automotive applications. It integrates high-side and low-side drivers with a three-phase BLDC motor controller featuring Hall sensor inputs. The device operates within a supply voltage range of 4.5V to 27V and supports continuous output currents up to 1.5A per phase. It includes comprehensive protection mechanisms such as overcurrent, overtemperature, undervoltage lockout, and shoot-through prevention. Packaged in a 20-lead SOIC (DW) surface-mount case, it meets AEC-Q100 automotive qualification standards.

Procurement Notes

Verify the specific suffix 'DWR2G' corresponds to the SOIC-20 package and tape-and-reel quantity when ordering. Confirm that the component meets the required AEC-Q100 grade for your specific automotive application environment. Ensure compatibility with your system's Hall sensor signal levels and supply voltage constraints before finalizing procurement.

Selection Notes

Select this component for applications requiring an integrated solution for driving three-phase BLDC motors with Hall sensors. It is suitable for designs needing built-in protection features to enhance system reliability. Consider the thermal performance of the SOIC-20 package relative to your expected current loads and ambient temperature conditions.

Part Context

This part belongs to the NCV series from onsemi, which focuses on automotive-grade electronic components. The NCV33033 family provides complete drive solutions for brushless DC motors, simplifying design complexity by integrating control logic and power drivers into a single IC. This integration reduces board space and component count compared to discrete solutions.

Replacement Considerations

Check for direct pin-to-pin replacements within the NCV33033 family or other onsemi BLDC controllers. Verify that any substitute maintains the same voltage range, current capability, and package dimensions. Ensure the alternative component also holds necessary automotive certifications if used in regulated environments.
