I was reading ADuM4121 datasheet.
I understood that ADuM4121 can detect mirror clamp at 2V.
So my questions are these.
Is it possible to change threshold voltage?
I think for GaN, 2V is too high.
If the Vclamp goes lower than 2V, how fast can ADuM4121 shutdown the gate.
I want to know the device delay.
1) The Miller Clamp on the ADuM4121 is set to 2 V typical, and cannot be changed without a silicon revision.
2) On the falling edge of the gate drive, once the output voltage has fallen below the Miller Clamp threshold (1.75 V min, 2.25 V max), there is an approximately 45 ns delay before the internal Miller Clamp turns on. This value is not production tested, so I can quote you a min and max, unfortunately.
Thank you for your reply.
