BD18347EFV-M
内置热分散电路 40V 150mA 4通道 车载用LED驱动器
BD18347EFV-M是4通道线性LED驱动器，可通过1个引脚控制多个输出的热分散。不仅可显著减少部件数量和安装面积，还非常有助于平台化扩展机型的汽车LED灯驱动模块电路板的通用化设计。可用于车后灯(刹车灯、尾灯)、雾灯、转向灯、牌照灯、日间行车灯(Daylight Running Lamps)等汽车和摩托车领域的众多LED灯驱动。
产品内置LED开路检测功能、OUTx（之后全部为 x=1～4）引脚输出接地故障保护功能、过电压静音功能及热关断功能，可实现高可靠性。连接于输出引脚的LED如果是2段的，请使用BD18347EFV-M；如果是3段的，请使用本BD18337EFV-M。

- Evaluation Board - BD18347EFV-EVK-101
This is an evaluation board for ROHM’s LED Driver BD18347EFV-M. BD18347EFV-M is 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.
