Key Document


This reference design is a sensorless BLDC motor sinusoidal drive using the DRV10983-Q1 motor driver and MSP430G2553 microcontroller (MCU). The MCU is only used for speed control while the DRV device is the main motor driver with integrated FETS which drives the motor. This design specifically targets small motor modules, particularly fans. This design allows access to proprietary sensorless control and the ability to tune motor parameters to optimize performance for the end application.

  • 12-V drive capable of driving 3 phase brushless DC (BLDC) motors with sinusoidal commutation
  • Single-layer design reduces manufacturing cost
  • Uses proprietary sensorless control scheme to provide continuous sinusoidal drive, significantly reducing pure tone acoustics
  • MCU processes speed input, control loop, and programs motor parameters
  • Output slew rate and frequency configurability offered from DRV10983-Q1 adds flexibility to tune for EMC performance
