50V 500mA 1-Channel LED Source Driver for Automotive - BD8374HFP-M
BD8374HFP-M is a LED source driver with the capability of withstanding high input voltage (50V Max.). The fixed current output is possible by PWM brightness, and it is suitable for automotive LED drive. It is built into LED open/short protection and overheating protection at over voltage, and high reliability can be achieved. When driving two or more LED by using two or more LSI, it can be done to control LED all together turning off even if LED causes short/open in a certain row.
