For Automotive, 40V 150mA 4ch Constant Current LED Driver - BD18347EFV-M
BD18347EFV-M are 40V-withstanding constant current LED driver for automotive applications. It is a 4 channel LED driver with the built-in energy sharing control which can realize to make the board size small. High reliability can be realized with LED Open Detection, the OUTx (all later x=1 to 4) pin Short Circuit Protection, Over Voltage Mute and Thermal Shutdown Function. In case the output OUTx pin has 3 LEDs in series, BD18337EFV-M has to be used, in case of 2 LEDs in series, this BD18347EFV-M has to be used.
