UF2768 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 mutation control, Pulse Width Modulation (PWM) speed control, lock protection, and thermal shutdown circuit.
