Bi-CMOS IC
CD/MD System Motor Driver
Overview
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.
Features
• Direct PWM drive (low side control)
• Three-phase full-wave sensorless motor driver (spindle and sled blocks)
• Soft switching drive (spindle block)
• Reverse torque braking
• MOS output transistors
• Standby mode power saving function
• FG output
