LB11852RV Features

* Single-phase full-wave driving pre-driver ⇒ With a PMOS-NMOS device used as the external power transistor, low saturation output and a single-phase full-wave drive enable a high-efficiency drive with low power consumption.

* Speed control circuit incorporated ⇒ Compared with open-l
