描述
BD18337EFV-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(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。

General Description  
Key Specifications  
BD18337EFV-M  
/
BD18347EFV-M  
are  
40  
Input Voltage Range:  
5.5 V to 20.0 V  
150 mA/ch  
±5 %  
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.  
Maximum Output Current:  
Output Current Accuracy:
