    UNISONIC TECHNOLOGIES CO., LTD UF2768 Preliminary THREE-PHASE SINE-WAVE SENSOR-LESS FAN MOTOR DRIVER  DESCRIPTION The UF2768 provides all the circuitry for sensor-less speed control of three-phase brushless DC motor. The Sine-wave Driver Method will be better low-noise. The controller functions include start-up circuit, back-EMF commutation control, Pulse Width Modulation (PWM) speed control, lock protection, and thermal shutdown circuit. The UF2768 is suitable for both game machine and CPU cooler that need silent drivers.
