BD8372HFP-M/EFJ-M is 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 autmotive 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 LSI, it can be done ～ control LED all together turning off even if LED causes short/open in a certain row.
