LV8224T
Bi-CMOS LSI
Motor driver system in CD and MD players
Overview
The LV8224T is a system motor driver IC that implements all the motor driver circuits needed for CD and MD products.
The LV8224T 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 LV8224T 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.
Features
• PWM H bridge motor divers (2 channels)
• Three-phase stepping motor driver, and direct PWM sensorless motor driver
