LB11870 Three-Phase Brushless Motor Driver

Ordering number : ENN7256 Monlithic Digital IC LB11870 Three-Phase Brushless Motor Driver for Polygonal Mirror Motors Overview 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 i.
