LB11852RV: Single-Phase Full-Wave Fan Motor Pre-Driver with Speed Control Function
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 can be implemented. The LB11852RV, integrated in a miniature package, is best suited for driving small fan motors requiring speed control.
