Three-Phase Brushless Motor Driver

for Office Automation Applications

Overview

The LB1922 is a single-chip drive circuit that provides the

direct PWM drive output appropriate for the power

brushless motors used in office automation equipment. It

provides a variety of peripheral circuits on chip, including

With an arbitrarily

large heat sink

a speed control circuit and an FG amplifier. It is optimal

in systems that use a 12-V power supply.
