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.
