Part Number: ISOUSB111
Other Parts Discussed in Thread: ISOUSB211, SN6507

Hello, My device is USB Device application. I want isolation in transfer of USB signals & power from Host. I found AD part LTM2884, is there an equivalent part with TI ?  Part ISOUSB111 does not transfer isolated power.

    Hi KrnB,

    Thanks for reaching out.

    We currently do not have isolated USB device with isolated power integrated. The best solution we currently offer is ISOUSB111 or ISOUSB211 paired with an isolated power supply solution. There are many isolated power solutions that you can use and the one that I would recommend is to use SN6505 / SN6507 devices which support high output current.

    Let me know if you have any other questions, thanks.

    Thank you for the reply. 

    Regarding SN6505, are there any recommended off the shelf transformer ?

    Hi KrnB,

    Yes, we do have a list of off the shelf transformers listed in the datasheet of SN6505. Please refer to Table 9-3 titled "Recommended Isolation Transformers Optimized for the Device" that lists many transformers. Let me know if you have any further questions, thanks.
