3-Phase Motor Driver IC

ON Semiconductor's LB11685AV, LV8804FV and LV8805SV are 3-phase sensor-less motor driver ICs that enable low power consumption and low vibration. The Hall sensor-less drive allows reduction of the size of the overall motor drive system. These ICs are suitable for use in products that require high reliability and long life such as server and refrigerator fans.
