LB1971V, Three-Phase Full-Wave Sensorless CD and MD Players Spindle Motor Driver

Ordering number :ENN6214A Monolithic Digital IC LB1971V Three-Phase Full-Wave Sensorless CD and MD Players Spindle Motor Driver Overview 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.
