Polygon Mirror Scanner Driver IC
Overview
The LB1872 is a 3-phase brushless motor driver IC developed for driving the polygon mirror motor used in laser printers and similar products.
braking (free running when stopped) • Built-in FG and error amplifiers • Full complement of protection circuits, including thermal protection, low voltage protection, and current limiter circuits, provided on chip.
Functions and Features
• Integrates the circuits (speed control and driver circuits) required for laser printer polygon mirror motor drive in a single chip.
• Uses a current linear drive technique for minimal motor noise.
