LB11872H
Three-Phase Brushless Motor Driver
for Polygonal Mirror Motors
Overview
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.
Functions and Features
• Three-phase bipolar current linear drive + midpoint
control circuit
• PLL speed control circuit
• Speed is controlled by an external clock signal.
• Supports Hall FG operation.
• Built-in output saturation prevention circuit
• Phase lock detection output (with masking function)
• Includes current limiter, thermal protection, rotor
constraint protection, and low-voltage protection circuits
on chip.
• On-chip output diodes.
