Brushless DC Motor Drivers

Brushless DC motors (BLDC), or electronically commutated motors (ECMs) have become more relevant in today’s environment where efficiency and minimizing power losses are a key objective of designs in all markets.  Brushless DC motors provide significant improvements in efficiency, mechanical reliability, and offer superb torque-to-weight properties. 

Allegro MicroSystems plays a key role in enabling brushless DC motor adoption by simplifying the complexities of electronic commutation.  Allegro offers a range of products targeted at BLDC applications which span the industrial, consumer, and automotive markets.  Depending on the needs of a given application, Allegro products can offer integrated features such as:

• Self commutating six-step / trapezoidal state machine with Hall sensor inputs
• Sensorless and sinusoidal commutation
• Back EMF sensing capability
• Automotive grade ICs with diagnostics and robust protection features
