LB11852FV-MPB-E Datasheet PDF - ON Semiconductor

●The LB11852FV 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 LB11852FV, integrated in a miniature package, is best suited for driving small fan motors requiring speed control.
