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.
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. Only a small capacitors are required for output
oscillation prevention.
PLL speed control adopted for high-precision rotation
with excellent jitter characteristics.
Phase lock detection output with a chattering prevention
function
Four rotation rates can be set up using a single crystal
oscillator to support 240, 300, 400, and 600 dpi
operation.
Arbitrary rotation rates can be acquired when an
external clock is used.
Deceleration function implemented by short-circuit
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.
