Part Number: TPS2546

Hi,

My customer is using TPS2546 for the testing of charging port need BC1.2.

But the GRL test fail during item EL_8 J.

It seems that once using charging controller, it will fail at the testing.

Customer want to know if there are ways to pass this test item or if this item should not be tested for the USB port with charging controller?

Please let us know if further information needed.

Thanks for your help.

Hello,
Would you be able to share with the test specification that the GRL tester follows? I would like to know the procedure that the GRL tester follows for these specific tests, do get a better understanding of why it may be failing.

Also, what setting does your customer have the TPS2546 in while this test is running?
