UCC37321: UCC37321, UCC37322 max "in" pin voltage

Part Number: UCC37321

Dear TI experts,

I want to make 2x ucc37321 being in parallel that is connected directly to eachother pin for pin  in order to enlarge the output current , Is that ok ?

Thanks,

John

  • Hi John,

    Due to potential mismatches between ICs, this is not recommended.

    If you can explain a little more about what you are trying to do, we can help you find a solution.

    Hi Don Dapkus,

    Thanks for your supports!

    I have not resolved the issues . For my concern, I want to get a 15A or more current's mosfet driver that is for driving a gate- drive transformer, then to drive some big power IGBT or mosfet via the transformer.

    Thanks,

    John

    Hi John,

    It's a little different direction, but you could eliminate your gate drive transformer and drive the gate directly with one of our isolated gate drivers. The UCC5390 has 17 A of typical gate drive current, so it sounds like it would be perfect for you. Take a look and let me know your thoughts.
