• Noise filter on power line for ADuM1100

    Dear Sir.Madam,

    I have a question for your ADuM1100 i-coupler,

    Our customer is proceeding to pwb design to use ADuM1100.

    So as for the power supply,

    Should we put the LC filter on the power-line for switching noise reduction like return back to power…

  • ADuM1100 vs ADuM110N

    Hello,

    ADuM110N is suggested as a pin2pin replacement for ADuM1100.

    The first one seems to have a feature which is not mentioned in the second's DS: fail-safe output.

    Does ADuM1100 provides any mechanism of setting the outputs to a certain value…

  • ADuM1100: Disfunction - burning out

    We use ADuM-1100 iCouplers. Some of them burn out. They are pumping current
    from output supply. Can you tell me what can be the cause of this problem ?

    We tough to a too high output current (1mA). Is it possible ?

     

    There are a few things…
  • ADUM1100: Different supply voltage

    Could I applied different supply voltage (ex. Vdd1=5V & Vdd2=3,3V) on ADuM1100?

     

    Although the units work at the voltages you describe, we have concluded that we
    cannot guarantee such performance over all temperature, supply voltage,…
  • RE: ADuM1200 drive MMBF170L mosfet

    Also Weidong, the ADuM1100/1200 are older generation products. The latest generation is ADuM110N (1-ch) and ADuM120N (2-ch). They are more cost-effective and have better performance and robustness.

    最近在做逆变器,功率管IGBT需要隔离,想到变压器隔离,但制作变压器比较麻烦,一致性不强。又想到光耦隔离,但光耦的价格很贵和驱动光耦的电流较大;一次偶然的发现了ADUM1100,速度很快,几乎没有延迟,这个芯片使用必须有良好的屏蔽,而且焊接温度不能太高,有好几次都让我烫坏了,找了半天的原因。总之,使用此款芯片要小心谨慎,采用参数表的指示来进行layout。

  • ADuM1100: Overvoltage when the output is shorted out

    I am using magnetic isolators in an isolated gate drive circuit which is
    typically operated at around 20kv/µs.

    The data sheet for ADuM1100 says this is OK.

    However there is a strong possibility the output will be shorted out in which…
