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

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,

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.

这是所有的原理图,请您指点一下。现在上管的供电一直有问题
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。
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…
I bought a GaN driver (ADUM4121) from ADI company for GaN short circuit test.
Figure 1 in the attachment is the schematic diagram of short circuit test. The principle of the whole short circuit is: first supply power to the left and right of adum4121…
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…
