Monolithic Digital IC

LB1696

3-phase Brushless Motor Driver

Overview

The LB1696 is a 3-phase brushless motor driver IC that is
ideal for driving DC fan motors in air conditioners, hot-water
supply systems, and the like. The LB1696 has a regulator built
in, and can be used with a single power supply (motor power
supply only).
