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 sensorless drive method for the spindle driver and the sled driver makes it possible to implement high efficiency motor drive with few external parts.
