Ordering number : EN7811A LV8220FN Overview Bi-CMOS IC CD/MD System Motor Driver The LV8220FN is a system motor driver IC that implements all the motor driver circuits needed for CD and MD products.

Since the LV8220FN provides a three-phase PWM spindle driver, a three-phase sled driver, and focus and tracking drivers (as two PWM H-bridge driver channels), it can contribute to further miniaturization, thinner from factors, and lower power in end products.

The adoption of the direct PWM sensor
