I would like to use ADuM4223.
So, I have a question. Please help me.
I am experimenting with ADuM4223.
In this situation, the phenomenon that the IC that supplies power to the ADuM4223 broke down (supplying power to VDDA and VDDB) occurred.
We are investigating the internal structure of ADuM4223 to investigate the cause.
For example, do you have CMOS inside?
We consider the possibility of power supply short circuit when a negative bias is applied to the pin.
I would like to know if there are other possible causes.
The ADuM4223 was not out of order.
