Other Parts Discussed in Thread: TUSB2077A, TUSB2046B, TUSB2036, TUSB1210

Hi Team,

Customer is asking whether we have isolated usb2.0 full speed solution right now? It could be a great help if we have related TIDA or App notes.

Thank you so much!

Hi Marc,

Unfortunately, we currently do not have isolated USB solution in our isolation portfolio. Thanks.

Hi Kotes,

Thanks for your reply. Could we use USB product + digital isolator to do that?

Thank you!

Hi Marc,

Regarding the discrete implementation of USB isolation, digital isolators like ISO77xx can be used to isolate USB provided the MCU supports ULPI interface and uses an external USB transceiver like TUSB1210. The ULPI interface between MCU and TUSB1210 follows standard digital logic levels and hence, these channels can be isolated using multiple channels of digital isolators between the MCU and TUSB1210.

Please do refer to the below E2E post for more details, thanks.
