BD8372HFP-M,BD8372EFJ-M

〔Please set after considering power consumption for the power-supply voltage.〕

BD8372HFP-M and BD8372EFJ-M are a LED source driver with the capability of withstanding high input voltage (50V MAX).

The fixed current output can change in the H/L current, and it is the best for automotive LED drive. It is built into LED

open/short protection, external resistance open/short protection and overvoltage overheating protection and high reliability

can be achieved. When driving two or more LED by using two or more IC, it can be done to control LED all together turning

off even if LED causes short/open in a certain row.

For automotive (Lear lamp, Interior light, etc.)
