Datasheet Summary
Ordering number : ENA1773
Monolithic Digital IC
3-phase sensor less Motor driver
Overview
The LB11685VH is a three-phase full-wave current-linear-drive motor driver IC. It adopts a sensor less control system without the use of a Hall Effect device. For quieter operation, the LB11685VH Features a current soft switching circuit and be optimal for driving the cooling fan motors used in refrigerators, etc.
