Overview
For Polygonal Mirror Motors
Three-Phase Brushless Motor Driver
The LB11876 is a 3-phase brushless motor driver developed for driving the polygonal mirror motor in plain-paper copiers and similar products. It can support any motor voltage and motor current required by the use of appropriate external ponents. The LB11876 adopts direct PWM drive to achieve drive with minimal power loss.
