Hi,

I received the question from my customer.

Does the TPS2549-Q1(or the TPS254900-Q1) have the result passing the surge test of ISO7637-2?

The test is p.15~16 of the attached file.

And please let me know how to pass the surge test of ISO7637-2 on the USB charger if you have information.

Best Regards,

Kuramochi

Hi Kuramochi,

Do you mean section 5.6.3 (Test pulses 3a and 3b)? Meaning PDF page including title/appendix or page # at the bottom of the documents?

Hi Kuramochi-san,
Sorry, we don't have such test data, do you need a formal test certification or just need a test result according to the ISO7637-2?
