LV8224FN ^{Motor driver system in CD and MD players}
Overview
The LV8224FN is a system motor driver IC that implements all the motor driver circuits needed for CD and MD
products. The LV8224FN provides a three-phase PWM spindle driver, a sled driver (either three-phase or PWM H
bridge operation can be selected), and focus and tracking drivers (as two PWM H bridge driver channels). Since the
LV8224FN uses BICDMOS devices, 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 makes it possible to implement high-
efficiency motor drive with few external parts.
Functions
• PWM H bridge motor drivers (2 channels)
• Three-phase stepping motor driver, and direct PWM sensorless motor driver
