Three-Phase Brushless Sensorless Motor Driver

for Headphone Stereo Motor Drive

Overview

The LB11676V is a three-phase brushless motor driver

that is optimal for portable electronic equipment such as

headphone stereos and microcassette recorders. The

LB11676V supports implementing power saving drive

techniques using an external capacitor and can achieve

lower power consumption levels than earlier devices.
