Monolithic Digital IC
LB1922
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
a speed control circuit and an FG amplifier. It is optimal
in systems that use a 12-V power supply.
