Bi-CDMOS IC
Motor driver system in CD and MD players
Overview
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.
Functions
• PWM H bridge motor drivers (3 channels)
• Three-phase stepping motor driver
• Half-bridge driver
• Direct PWM sensorless motor driver
