LB11683V ^{Monolithic Digital IC}
Three-Phase Sensorless Motor Driver
Overview
The LB11683V 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 LB11683V features a current soft switching circuit and
is optimal for driving the cooling fan motors used in refrigerators, etc.
