AFE3010: 应用咨询

Part Number: AFE3010

您好.

有几个关于AFE3010 问题:

1. SCR (Pin 6)

    1. 输出电压范围是多少V ?输出电压值 大小受那些因素影响?
    2. 输出脉冲 宽度是多少ms?脉冲 宽度受那些因素影响?

 2. ALARM (Pin 7):

    1. 漏电触发后, Self-Test 功能是否停止工作?
    2. 漏电触发后,输出是否一直维持以下状态?
    3. 如何恢复ALARM 原始(低电平)状态?除重新上电还有什么方法?

     

    3. SCR_TST (Pin 9):

      1. 规格书应用电路建议连接电阻(R11 )为51K,1%,若产品供电 120Vac ,60Hz  或 240V, 60Hz 均可,电阻(R11)建议使用多大?

     4.  "7.3.7 self-test function : The AFE3010  performs two different types of self-tests: periodic self-test and continuous self-test"

      1. Periodic Self-Test  是否对应方块图 Figure 10?
      2. 有没Continuous Self-Test方块图?

       

      5.  关于上电 VDD 电压上升时间,datasheet 备注“if the capacitance at VDD is too large,then the device takes longer to power up,which adds to trip times when device is powered up with a fault current."

        1. VDD上升时间有什么要求?是否相对某个IO 有时间关系 和要求?
