LB11872H中文资料LB11872H: Motor Driver, 3-Phase, Brushless数据手册ONSEMI规格书

描述 Description

The LB11872H is a three-phase brushless motor driver developed for driving the motors used for the polygonal mirror in laser printers and similar applications. It can implement, with a single IC chip, all the circuits required for polygonal mirror drive, including speed control and driver functions. The LB11872H can implement motor drive within minimal drive noise due to its use of current linear drive.
