• ADuM4121 Bootstrap setup

    I am trying to design the circuit referenced in the datasheet.

    Any guidance on selecting Rboot, Dboot, D1 and D2, and Rgaoff and Rgboff?

    I am using 4 of these parts in a Half Bridge circuit.  Vbuss is 340VDC and VDD2 is 15VDC.

    Thanks,

    Rich

  • About usage ADuM4121 as +6V/-3V GaN Driver

    Hello,

    I am investigating to use ADuM4121 as +6V/-3V gate driver for GaN E-HEMT.

    Can I use ADuM4121 on such as below circuit for +6V/-3V driver?

  • ADuM4121 Miller clamp pin leakage current

    Hello,

    I am wondering what the leakage current into the miller clamp pin is on the ADuM4121. I am unable to find it in the datasheet.

    Thanks,

  • ADUM4121-1-EP. Can i use in a bus voltage of 60V?

    Can i use the schematic of figure 31 with Vbus of 60V?

    Thanks

  • adum4121-1 voltage

    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.

    Regards

  • 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？

  • 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。

  • ADUM4121-ARIZ

    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…
