LB11868V中文资料Fan Motor Pre-Driver, Single-Phase, Full-Wave, Variable Speed数据手册ONSEMI规格书

描述 Description

LB11868V 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 and large current and the fan motor of consumer appliances.
