DS90UB953-Q1: Disconnect DS90UB953 from DS90UB954 while power supply is working

Part Number: DS90UB953-Q1

 Dear Sir,

In my case, my customer maybe disconnect the DS90UB953-Q1 board from DS90UB954 board while the system power is working, and POC power mode is used in my case.

Is there any damage risk for both of DS90UB953 and DS90UB954?

For example, the energy stored in Induce and Cap will go through the AC couple cap and into RX and TX pins , Can this energy damage 953 and 954?

Best regards,

David
