Overview
The NCV33039DR2G is a closed-loop brushless DC motor adapter manufactured by onsemi. It operates within a supply voltage range of 5.5V to 9V, with a maximum collector-emitter voltage (Vceo) of 7.5V. The device delivers an output current of 20mA and dissipates up to 650mW. It functions reliably across an operating temperature range from -40°C to +85°C. Packaged in an 8-pin SOIC format measuring 5mm x 4mm x 1.5mm, it serves as a high-performance speed control solution for BLDC motors.
Feature Summary
- Provides closed-loop speed control functionality specifically designed for brushless DC motors
- Integrates driver circuitry within a compact surface-mount package for simplified system design
- Operates at low supply voltages suitable for battery-powered or low-voltage applications
Applications
- Closed-loop speed control for general-purpose brushless DC motors
- Motor adaptation in consumer electronics requiring precise rotational speed regulation
- Industrial automation systems utilizing small BLDC actuators
Procurement Notes
Verify the specific suffix 'DR2G' against official onsemi documentation to confirm tape-and-reel packaging and lead-free status. Ensure the component meets AEC-Q100 automotive qualification requirements if intended for automotive environments, as standard MC33039 variants may differ. Cross-reference the datasheet revision date to validate electrical characteristics before finalizing procurement specifications.
Selection Notes
Select this component when a dedicated closed-loop adapter for BLDC motors is required rather than a standalone driver. Compare the 20mA output capability against load requirements to ensure adequate drive strength. Evaluate the 8-pin SOIC footprint constraints against available PCB space. Consider the -40°C to +85°C temperature range against environmental conditions to determine if extended industrial grades are necessary.
Part Context
This part belongs to the MC33039 series of brushless DC motor controllers. It is functionally related to the MC33039DR2G, with the NCV prefix typically indicating automotive-grade qualification. The series focuses on providing integrated solutions for speed control, distinguishing itself from open-loop drivers by supporting feedback mechanisms for stable motor operation.
Replacement Considerations
The MC33039DR2G is a confirmed equivalent substitute. Verify that the non-NCV variant meets the same thermal and electrical specifications for the target application environment.
