Overview
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.
