LB11867RV - Variable Speed Single-phase Full-wave Pre-driver

www.DataSheet.co.kr Ordering number : ENA1534A Monolithic Digital IC LB11867RV Overview For Fan Motor Variable Speed Single-phase Full-wave Pre-driver LB11867RV is a single-phase bipolar driving motor pre-driver with the variable speed function compatible with external PWM signal. With a few external parts, a highly-efficient and highly-silent variable drive fan motor with low power consumption can be achieved. This product is best suited for driving of the server requiring large air flow .

LB11867RV Features

* Single-phase full-wave driving pre-driver ⇒ Low-saturation drive using external PMOS-NMOS enables high-efficiency low power-consumption drive.

* Variable speed control possible with external PWM input ⇒ Separately-excited upper direct PWM (f =30kHz) control method ensures highly s
