LB11867RV Variable Speed Singlephase Fullwave Predriver for Fan Motor Monolithic Digital IC www.onsemi.com Overview 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 SSOP16 and large current and the fan motor of consumer appliances.
