LB1871, 1871M

Three-Phase Brushless Motor Driver

Overview

The LB1871 and LB1871M are three-phase brushless

motor driver ICs that are optimal for LBP and LBF

polygon mirror motor drive. The LB1871 and LB1871M

are versions of the LB1870 and LB1870M in which the

value of the divisor has been changed.

Functions and Features

• Single-chip implementation of all circuits required for

LBP polygon mirror motor drive (speed control and

driver circuits)

• Low motor drive noise level due to the current linear

drive scheme implemented by these ICs. Also, small

capacitors suffice for motor output oscillation

suppression, with certain motors not requiring these

capacitors at all.

• Extremely high rotational precision provided by PLL

speed control.

• Built-in phase lock detector output

• Four motor speed modes set by switching the clock

divider provided under internal clock/crystal oscillator

operation. This supports 240, 300, 400 and 480 dpi.

• Use of an external clock allows arbitrary motor speeds.

• Built-in FG and integrating amplifiers

• Full set of built-in protection circuits, including current

limiter, undervoltage protection, and thermal protection

circuits.
