LB11868V Overview
ENA1915A LB11868V Monolithic Digital IC For Fan Motor Variable Speed Single-phase Full-wave Pre-driver http://onsemi. Overview LB11868V is a single-phase bipolar driving motor pre-driver with the variable speed function patible 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.
