For Polygon Mirror Motor  
LV8111V  
3-phase Brushless Motor Driver  
Overview  
The LV8111V is a 3-phase brushless motor driver for polygon mirror motor driving of LBP.  
A circuit needed to drive of polygon mirror motor can be composed of a single-chip. Also, the output transistor is made  
DMOS by using BiDC process, and by adopting the synchronous rectification method, the lower power consumption  
(Heat generation) is achieved.  
Features  
3-phase bipolar drive  
Full complement of on-chip protection circuits, including lock  
protection, current limiter, under-voltage protection, and thermal  
shutdown protection circuits  
Circuit to switch slowing down method while stopped  
(Free run or Short-circuit brake)  
Direct PWM drive + synchronous rectification
