LB11852RV Description
ENA2133 LB11852RV Monolithic Digital IC For Fan Motor Single-phase Full-wave Pre-driver with Speed Control Function http://onsemi. Overview The LB11852RV is a single-phase bipolar driving motor pre-driver with a speed control function based on speed feedback. With a small number of external parts, a highly efficient and very quiet variable-speed drive fan motor with low power consumption and high rotational accuracy...
