• (ADuM3224)Short output

    Hi 

    Customers are looking for a gate driver with a drive capacity of around 7A.

    What is needed is an insulated gate driver.

    Is it okay if the outputs of the ADUM3224 are short-circuited and driven in parallel?

    Personally, I am worried that I can not switch…

  • ADUM3224 VOA output Abnormal

    Hello  everyone

           I want  use ADUM3224 to bulid H-bridge inverter. But the problem is that when VddA=12v   Vdd1=0v   VoA=GNDA=11.5V  .  Is that something wrong?   what can i do!

  • ADUM3224

    Hello,

    I'm designing a synchronous CUK converter so i need to use one of the analog devices isolated gate driver ICs which in my case would be ADUM3224. Is there any LTspice model available for this part (ADUM3224)? I would appreciate if you provide me…

  • ADuM3224 : The delay time from input VDDA(VDDB) to output VOA(VOB)

    Hello ,

    I have a question about transition when ADuM3224 was powered on.
    The VDD1 is powerd on before VDDA(VDDB), and the VDDA(VDDB) is powered on after VDD1.
    VDDA is powered on after VDD1 more than 100ms later.
    The VOA(VOB) will be setup with some delay…

  • Spice Model for Isolated gate driver (ADuM3224)

    Hi

    The customer will evaluate ADuM3224, and they want to simulate it with spice model.
    I understand that we can provide only IBIS model for ADuM3224.

    And I saw your comment as follow:

    ADuM7223因为封装不好焊接,所以想找个替代的,不知道能不能用ADuM3224代替,电路又需要怎么变化?

  • RE: LTC3779 use in non-synchronous buck-boost converter

    Hi 

    For Question 2, 

    Can you discuss more on the reason on why you aim to use adum3224?

    My initial assumption is that you needed an isolated power supply that is why I have suggested Fly back controllers. 

    For Question 3,

    as can be seen on the block diagram…

  • RE: Hello. I want to know if the ouput of the ADuM3221 gate driver are isolated between them?

    Hello,

    The ADuM3221 has two outputs, but they share the same output ground. If you need two output channels that can be separated by 400 V, the ADuM3223, ADuM4223, and ADUM7234 are some solutions. There are also the ADuM3224 and ADuM4224 which are the…

  • RE: ADuM4223/4224 差別與應用

    ADuM3224内部没有thermal shutdown功能。

    可以的,请注意一下ADuM322x不同的UVLO版本。
