LV8224T, Motor driver system

Ordering number : ENA0793B LV8224T Overview Bi-CMOS LSI Motor driver system in CD and MD players 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 miniaturiz
