DS2406双通道可寻址开关的应用

单总线技术用一根信号线传输数据、地址、控制三种信令，并通过一根地线构成回路。同时单总线主设备还可以为挂接在总线上的单线器件集中馈送电源，这种提供电源的方法称之为“寄生电源”技术。由单总线技术构建的测控系统具有结构简单、布设方便、经济性好等优点。利用单总线主设备为挂接在网络上的单线器件提供电源的方法有很多，电路结构也各不相同。在本文中，我们讨论几种从单总线获取电源的方法，并介绍DS2406双通道可寻址开关在其中的应用。

The Using of DS2406 Dual Addressable Switch

1 - Wire chips get both their power and communication over the same line , making the connections extremely economical . When adding power-consuming devices to a 1 -Wire node , the same line can also supply power to them using one or more of the technique described here . In this paper will review some methods for providing power on the net including a technique for accumulating low-level energy and releasing it as a high energy burst on demand . And ,we'll introduce the DS2406 and it's using in the system of supplying power via the 1 -wire bus .
