Datasheet For Automotive, 40 V 150 mA 4ch Constant Current LED Driver BD18337EFV-M BD18347EFV-M General Description BD18337EFV-M / BD18347EFV-M are 40 V-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, BD18347EFV-M has to be used.
