Three-Phase Full-Wave Sensorless CD

and MD Players Spindle Motor Driver

Overview

Package Dimensions

unit: mm

The LB1971V is a bipolar sensorless motor driver that

provides a reverse torque braking function and is

appropriate for use as the spindle motor driver in CD and

MD players. Since the LB1971V can drive motors without

the use of Hall elements, this device can contribute to

miniaturization, thinner form factors, and lower power

dissipation in end products.
