Part Number: TPS2511-Q1


Hi team

Attach the block diagram.
What happens when EOS (Electrical Overstress) is applied to the DP or DM port?
More than 2KV.

Please use the block diagram to explain.

Thanks,

TM

    Hi, TM,

    The part will be damaged if >2KV EOS is applied to DP/DM. Because this part max ESD rating is 2kV. If there's risk of >2KV ESD, you can add external ESD protection part.

    Feel free to ask any questions.

    Regards,

    Bob

    Hi Bob

    Could you please explain the situation in the above block?

    S1, S2 and S3 switches are open.
    Damage is expected to occur only in certain situations.

    Thanks,

    TM

    TM,

    S1,S2 and S3 are low voltage FET, if EOS applied, these FETs will be damaged and leakage current from DP/DM to ground will increase, which means the resistance from DP/DM to GND will decrease.

    Bob
