General Description

Key Specifications

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.
