• (ADuM4121)How fast can ADuM4121 detect mirror Clamp?

    Hi !

    I was reading ADuM4121 datasheet.

    I understood that ADuM4121 can detect mirror clamp at 2V.

    So my questions are these.

    Q1)

    Is it possible to change threshold voltage?

    I think for GaN, 2V is too high.

    Q2)

    If the Vclamp goes lower than 2V, how fast…

    Hi,

    Why ADUM4121-1TRIZ-EP can not be driven by 5 volts?

    I asked this question because in datasheet It can be.

    Thank you in advance for your time and consideration.

    Hi,

    I'm not able to understand how to use Vi+ and Vi- pins of the driver.

    GaN Systems has a half bridge eval board based on ADUM4121A. They have following connections- 

    Is it necessary to provide a complementary input to each driver? Can I just…

  • 关于ADUM4121

    采用ADMU4121来驱动氮化镓半桥电路，采样的全隔离的驱动方案，但是现在上管的驱动电压随输入电压的升高而升高，不知道为啥？是因为驱动芯片的原因吗？上管是将5V的输入电压由B0515隔离芯片转化为隔离的15V在由SY8120降压到6V给上管的ADUM4121供电，但是这个6V电压在随主电路输入电压的升高而升高，有人指点一下吗？

    HI

    I have a question ADUM4121.

    Figure17 is Peak Output Current.

    Is it  also no problem by this Figure17 current ?

  • ADUM4121电源问题

    ADUM4121的左右供电分别是VDD1、DGND和VDD2、PGND，如果DGND和PGND通过零欧电阻单点连接会有什么影响吗？就相当于ADUM4121左右的地不是完全隔离的。

    Hello,
    Is there Spice-Model for ADuM4121-1? I've tried with help of "IBIS2SPICE" the IBIS Model transfered into Spice-Model. However, there is still a Problem, when I use the Spice-Model in LT-Spice, the Model can not be recognized. …
