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.
Funciones
- Small form factor (55mm diameter PCB, singlesided component placement)
- Low sleep current (<100μA maximum)
- 70V LIN bus fault voltage robust LIN communication in 48V architecture
- Ready-to-use field-oriented control (FOC) algorithm plus royalty-free microcontroller abstraction layer (MCAL) driver (local interconnect network [LIN] 2.x and approximately 50Hz to 10kHz pulse width modulation [PWM])
- Sleep and wake over LIN
- Flexible communication interface supports LIN2.x and PWM (about 50Hz to 10kHz PWM)
