com Monolithic Digital IC LB11873 Overview For Polygonal Mirror Motors Three-Phase Brushless Motor Driver 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.
Functions • Three-phase bipolar drive (quiet direct PWM) • PLL speed control circuit • Hall sensor FG support • Dedicated external clo...
