50V 200mA 1-Channel LED Source Driver for Automotive - BD8372HFP-M

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 over voltage 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.
