Overview
The MC33039D is a high-performance closed-loop speed control adapter designed for brushless DC motor systems. It enables precise speed regulation without magnetic or optical tachometers. The device operates on a 5.5 V to 9 V supply with a maximum collector-emitter voltage of 7.5 V and output current of 20 mA. It features three hysteresis input buffers, digital edge detectors, a programmable monostable, and an internal shunt regulator. Operating temperature ranges from -40 °C to 85 °C in an 8-pin SOIC package.
Feature Summary
- Digital detection of each input transition for improved low-speed motor operation
- TTL compatible inputs with hysteresis for noise immunity
- Internal shunt regulator allows operation from a non-regulated voltage source
- Inverter output for easy conversion between sensor phasing conventions
Applications
- Brushless DC motor control systems
- Closed-loop speed control applications
- Systems requiring precise speed regulation without external sensors
Procurement Notes
Verify the specific suffix against official documentation to confirm package type and compliance status. Ensure the ordering part number matches the required tape and reel or tube configuration. Confirm RoHS and lead-free status through the manufacturer's latest datasheet or compliance declaration before procurement.
Selection Notes
Select this component when designing closed-loop BLDC controllers that require integrated phase sensing adaptation. It is suitable for direct powering from regulated sources near 5.5 V to 9 V. Consider its compatibility with the MC33035 controller for complete system integration. Evaluate thermal performance within the specified operating temperature range.
Part Context
This component belongs to the MC3303x series of brushless motor adapters. It serves as a companion to the MC33035 controller, providing necessary signal conditioning and phasing logic. The family focuses on cost-effective solutions for sensor-based BLDC applications.
Replacement Considerations
Check for MC33039DR2G or MC33039DG variants for identical functionality in different packaging formats. Verify pinout compatibility if substituting with other closed-loop adapters.
