TS3USB3000: Bir-direction connection issue

Part Number: TS3USB3000

Hi,

We got  high fail rate for device return from customer. Customer have design USB connector side connect to USB+/- and MHL+/- pin of TS3USB3000. I think it's not bir-direction connection and maximum voltage rating of USB-/MHL- should over 5.5v  in case using USB charging. It should be damaged on  pin USB-/MHL- when use USB charging. Does it correct?

    Hello Jimmy,

    All voltage levels supplied to the TS3USB3000 should be within the rages defined at section 6.3 of the datasheet.

    Battery charging applications shouldn't have a problem as VBus isn't passed through TS3USB3000.

    If you provide a more detailed (and higher resolution) schematic, I can help to review everything is in place.

    Regards,
    Jorge
