STMicroelectronics supplies state of the art microcontrollers and power MOS for a full kit solution. For a field oriented controlled 3-phase motor, the L6390 is an optimized choice. The integration of the operational amplifier, smart shut down, and bootstrap diodes allows the designer to decrease the bill of materials, and reduce the PCB space. ST developed libraries with the STM32 (32-bit ARM processor) running in conjunction with the L6390, optimizing torque and speed control, enabling the best accuracy with no positioning sensors.
