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.
Functions and Features
Three-phase bipolar sensorless drive
Soft switching drive technique
Reverse torque braking
Standby mode power saving function
FG outputs
Can be operated from a 3-V supply.
