Three-Phase Brushless Motor Driver  
for CD-ROM Spindle Drive  
Overview  
The LB1997 is a three-phase brushless motor driver  
Package Dimensions  
unit: mm  
especially suited for CD-ROM spindle motor drives.

Functions  
• Current linear drive  
• Control V type amplifier

0.2  
• Separate power supply for output upper side bias  
circuit allows low output saturation by boosting this  
power supply only (useful for 5V power supply types).  
• Upper side current detection technique reduces loss  
voltage of current detection resistor. Voltage effect of  
this resistor reduces internal current drain of IC.  
• Built-in short braking circuit
