Semiconductor Components Industries, LLC, 2014 March, 2018 Rev. 21 Publication Order Number: LB11867FV /DLB11867 FVVariable SpeedSingle phase Full wavePre driver for Fan MotorMonolithic Digital ICOverviewLB11867FV is a single -phase bipolar driving motor pre-driver withthe Variable Speed function compatible with external PWM a few external parts, a highly-efficient and highly-silent variabledrive fan motor with low power consumption can be achieved. Thisproduct is best suited for driving of the server requiring large air flowand large current and the fan motor of consumer single -phase Full-wave Driving Pre-driver Low-saturation Drive Using External PMOS NMOS EnablesHigh-efficiency Low Power-consumption Drive Variable Speed Control Possible with External PWM Input Separately-excited Upper Direc
