The LV8223T is a system driver IC that can implement, with a single chip, all the motor driver circuits required in CD and MD drives. The LV8223T provides three-phase PWM spindle, three-phase sled, focus, and tracking drivers. Since it integrates lifting drivers (three PWM H bridge channels) and one half-bridge channel on the same chip, it can contribute to further miniaturization, thinner form factors, and lower power in end products. The spindle motor driver adopts a direct PWM sensorless drive technique for highly efficient motor drive requiring a minimal number of external components.
