Description

General part information

BD18340FV-M Series

8018340FV-M is 70V-withstanding Constant Current Controller for Automotive LED Lamps. It is able to drive at maximum 10 rows of PNP transistors. It can also contribute to reduction in the consumption power of the set as it has the integrated stand by function. The IC also incorporates a highly reliable, in-built de-rating function, LED Open Detection, Short Circuit Protection and Over Voltage Mute function and LED failure input / output function.
