ADE7953电路设计中的问题

您好,我在初次使用ADE7953在智能PDU的检测,主要用于电能计量和电压/电流测量,在设计中有些问题,希望能够帮忙解答一下:

1. 电流检测通道

    ADE7953支持双通道电流检测,在当前项目中,我只需要检测一路通道电流,零线检测通道不使用,请问如果不使用零线检测通道,是否只是将Ibp,Ibn悬空即可,还是有其它特殊处理方式?

2. 外部通讯

   使用ADE7953对外通过SPI进行通信,仅使用了MISO/MOSI/SCLK/CS四条线,没有使用IRQ/CF1/CF2/ZX/ZX_I/Revp等信号,那么这些信号管脚也是悬空即可?还是做其他处理?

感谢!

  • Hi bryan,

    Apologies if I will not directly answer your question as this Q and A is in the English version of the Engineer ZOne though I asked someone to translate and hopefully I can answer this the best way.

    So your were asking:

    If IBP and IBN is just floating when IB channel not require.

    Answer: You can tie to GND.

     

    Another question is how about digital if not used. 

    Answer: You can leave floating if not used.
