UF2768 Datasheet (UTC) - THREE-PHASE SINE-WAVE SENSOR-LESS FAN MOTOR DRIVER

UF2768, THREE-PHASE SINE-WAVE SENSOR-LESS FAN MOTOR DRIVER

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, a
