LV8111VB
Bi-CMOS LSI
3-phase Brushless Motor Driver
for Polygon Mirror Motor
www.onsemi.com
Overview
The LV8111VB 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.
