LB11873:Three-Phase Brushless Motor Driver for Polygonal Mirror Motors
The LB11873 is a 3-phase brushless motor driver developed for driving the polygonal mirror motor used in plain-paper copiers and similar products. This IC can implement the circuits required for polygonal mirror motor drive (speed control and driver circuits) in a single chip. The LB11873 implements low-noise/low-vibration PWM drive by changing the current at phase switching gradually to reduce motor noise.
