LB11870

Three-Phase Brushless Motor Driver

for Polygonal Mirror Motors

Overview

Package Dimensions

unit: mm

The LB11870 is a three-phase brushless motor driver

developed for driving the motors used with the polygonal

mirror in laser printers and plain paper copiers. It can

implement, with a single IC chip, all the circuits required

for polygonal mirror drive, including speed control and

driver functions. The LB11870 can implement motor drive

with minimal power loss due to its use of direct PWM

drive.
