This reference design demonstrates a 48V, 300W peak smart motor brushless direct current (BLDC) implementation. The discrete approach enables compact and flexible form factors with diameters as small as 55mm. The design maintains low power sleep modes of less than 100µA. The design leverages TI semiconductors to facilitate efficient operation. The architecture provides a robust foundation for demanding automotive heating, ventilation, and air conditioning (HVAC) applications requiring high power, precision, and miniaturization.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
