The set with BQ51013 YEF which we have developed is not detected by TX pad, unexpectedly.
At current we'll do mass production after Qi certification.
I have never experienced this error, developing that.
In the testing for Qi at qualified test lab , at first well operated , but after some times , not detected.
I found same error with BQ500210EVM Tx , repeating the detection by attaching and detaching on the pad.
I don't know what test procedure is problematic. I doubt the BQ51013 is broken (not HW) by extremely changed magnetic field as different TX pads.
Is it possible to break down the BQ51013 by magnetic fields?
This can be caused by a number of problems.
Contact your local TI representative for additional assistance.
