ISO7740: ISO7740

Part Number: ISO7740
Other Parts Discussed in Thread: LM5110

Tool/software:

Dear Team,

Greetings!

We are currently working with the ISO7740 digital isolator in conjunction with the LM5110 gate driver IC. While simulating each component individually yields successful results, we encounter an error stating "incorrect number of interface nodes" when attempting to simulate both components together. We would like to clarify that we have not left any pins floating. All the pins are properly connected, yet we are still encountering the same error. I have attached the images of the circuit and the corresponding simulation error for your reference.

Could you please assist us in resolving this issue?

Thank you for your support.
