Hello William,

You may want to refer to the Functional safety information document available on the TPS62816-Q1 product page.

You will be able to find information you requested on Table4-2 and Table 4-3.

Let me know if you have any further questions.

Thanks a lot!

Dorian

Hello William,

Another document is available for TPS62813-Q1, also available on the product webpage under the Technical documentation section.

I don't think there is a big difference between those two.

Let me know.

Thanks a lot!

Hello William,

I would suggest, you have a look at each product webpage on ti.com under the Technical documentation section.

We may not have this document available for each device. If you don't find it. I recommend you open an E2E thread with the specific devices name and the specific functional safety document you are willing to have. We will try to support you our best to give you detailed information.

Each device may belong to different part of TI portfolio and would need a different expert to answer your question. This is why you would need to address your query for a specific device on a separate E2E thread.

For the time being, functional safety information of TPS62850x is here.

Let me know if you have any further questions.

Thanks a lot!

Regards,
Dorian
