TUSB2046B: How to recognize original TUSB2046B parts?

Part Number: TUSB2046B

Dear Sir:

We brought two different set of TUSB2046B hub from two different chinese suppliers. We are using them on the same board and same configuration: the one at image on top works with no any problems, but the second one at bottom place at image gave us a lot of problems; just about 30% of them works fine, most of them are with the fourth downstream not working. Other simple are dead.

As you can see Ti logo on components are different.

May be the second one at bottom place is not original part?

Does Ti changed its logo?

How to recognize original parts?

Best regards.

  • Hi Pacheco,

    According to our marking database we don't use any of those markings on TUSB2036B devices, so it seems that both devices are fake.
    I strongly recommend to purchase TI products on our web page or with any authorized dealer.

    Regards.
