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.
