Reka bentuk rujukan oleh: Texas Instruments
TIDA-00112, Reference Design provides a simple way to spin and control a 5V, 3-phase, BLDC fan motor with minimum development time and overhead. It utilizes the DRV10866, a sensorless BLDC motor driver, for the power stage and a TLC555 timer to provide a variable duty cycle PWM signal for speed control. The DRV10866 uses a 150 degree sensorless BEMF control scheme that takes away the need for external sensors on the motor
