Dear support team;

I want connect DS90UB913-Q1EVM and DS90UB954-Q1EVM.

I confirmed the following description.

I opened J17 and J18 on the DS90UB954-Q1EVM.

When I supply 12V via JP11 on the DS90UB913-Q1EVM, the device(DS90UB913) is warm.

When I supply 5V via JP4 on the DS90UB913-Q1EVM, the device(DS90UB913) is not warm.

Which is correct?

Best Regards,

Sugiyama-san,
You can either power the 913A EVM directly after you open J17 or J18 (POC disabled), or apply 5V to the 954 EVM via J17 or J18.
Basically the 913A EVM is designed for a maximum 5V PoC so higher voltage should be avoided to prevent damage.
