    Hi Choi,

    For case 1 thank you for bringing this to our attention. There seems to be some inconsistencies for which I will be reviewing this with the team in order to make the proper corrections where needed. I will inform you of our conclusion.

    Could you elaborate on case 2?  What are the exact testing conditions for the operation you are seeing? Is there a schematic you could share and/or waveforms?

    For case 3 I would like to get some clarification. When power VCC off you're measuring a reverse current internally from IN+/IN- to VCC? what are the testing conditions for this measurement? Is there a schematic you could share?

    For case 4 I'm not sure if this is a question or just a statement. The UCC21736-Q1 has the CLMPE pin which as described by the datasheet is to drive an external FET like you described.

    Let me know if there's any questions.

    Best regards,

    Andy Robles
