Datasheet
Constant Current LED Drivers for Automotive
Constant Current Controller
for Automotive LED Lamps
BD18340FV-M BD18341FV-M
General Description
BD18340FV-M/BD18341FV-M are 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 standby 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.
