Overview
The LB11683H is a three-phase full-wave current-linear-drive motor driver IC. It adopts a sensorless control system without the use of a Hall effect device. For quieter operation, the LB11683H features a current soft switching circuit and is optimal for driving the cooling fan motors used in refrigerators, etc.
