LB11850VA Features

* Pre-driver for single-phase full-wave drive →PMOS-NMOS is used as an external power TR, enabling high-efficiency and low-power-consumption drive by means of the low-saturation output and single-phase full-wave drive.

* On-chip speed control circuit →The speed control (closed loop c
