Features
- 24V, 35W Sensorless FOC drive capable of driving brushless DC (BLDC) motors
- Highly-integrated and protected single-chip, brushless FOC motor controller reduces external parts count and audible noise
- Integrated FOC algorithm with windmilling support, fast start-up, and quiet operation
- Support closed-loop speed control maintains high accuracy of expected motor speed
- Reliable start-up and fully-protected system with short circuit, overcurrent, and blocked rotor protection
- Single stage PFC to Achieve High Input Power Factor (> 0.92),universal input capability (85V to 265V AC) with minimum variation in efficiency
- Cost-optimized MCUs MSPM0C or MSPM0L offer high-performance analog peripheral integration
- Optimized small-form factor (SFF) fits for motor integration
