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.
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.
• Thermal protection circuit
