Monolithic Digital IC  
LB11872H  
Three-Phase Brushless Motor Driver  
for Polygonal Mirror Motors  
Overview  
Package Dimensions  
unit: mm  
The LB11872H is a three-phase brushless motor driver  
developed for driving the motors used for the polygonal  
mirror in laser printers and similar applications. It can  
implement, with a single IC chip, all the circuits required  
for polygonal mirror drive, including speed control and  
driver functions. The LB11872H can implement motor  
drive within minimal drive noise due to its use of current  
linear drive.
