LB1824
Power Brushless Motor Driver
for OA Equipment
Overview
The LB1824 produces the direct PWM drive output
appropriate for the brushless motors used in office data
processing (OA) equipment, and integrates on a single
chip the speed control circuits, FG amplifier, and other
circuits required to form the drive circuit.
