Basic Interoperability Question: Qi to Qi

Michael Banak
Intellectual 915 points
Other Parts Discussed in Thread: BQ51013

First, let me thank you for an exciting and impressive roll-out.

1) The 5W Qi standard is the going trend now, and this is good. But if I designed my own transmitter, (not using your impressive chip), and placed a Qi receiver on it, as long as my design complied with the standard, they *should* work together, right?

2) More specifically, if I run to Best Buy or Target and purchase a Qi-Compliant Energizer charging pad, and then lay the bq51013EVM-725 Evaluation Module right on top of it, wouldn't I see that little LED come up, indicating functionality?

I ask that 2nd question, because I think it all comes down to that. If I design around your receiver, My customers can use most any Q-Compliant transmitter. I expect these chargers to be "ubi-Qi-tous".

          It would be fun to know whether you have tried that Energizer idea on your own yet.

3) It looks like I still have to add my own little charger to the output of the bq51013EVM-725 Evaluation Module, right?

4) I am not seeking a recommendation here, but if you know about any other commercially available Qi-Compliant chargers, it would help us buy them to confirm interoperability.

Thanks again for all you do.

 

Yours truly

    Hello Michael

     

    The advantage of the Qi standard is interoperability between transmitters and receivers.  Any receiver can operate on any transmitter provided both are Qi-Compliant.  

     

    Q---The 5W Qi standard is the going trend now, and this is good. But if I designed my own transmitter, (not using your impressive chip), and placed a Qi receiver on it, as long as my design complied with the standard, they *should* work together, right?

    Ans—Yes

     

    Q---More specifically, if I run to Best Buy or Target and purchase a Qi-Compliant Energizer charging pad, and then lay the bq51013EVM-725 Evaluation Module right on top of it, wouldn't I see that little LED come up, indicating functionality?

    Ans--- Yes and we have done this test.  The bq51013EVM-725 will operate on the Energizer pad.

     

    Q---It looks like I still have to add my own little charger to the output of the bq51013EVM-725 Evaluation Module, right?

    Ans--- Yes, the bq51013 is a 5V power supply only. 

     

    Q---I am not seeking a recommendation here, but if you know about any other commercially available Qi-Compliant chargers, it would help us buy them to confirm interoperability.

    Ans--- There are none that I can recommend, but stay tuned to TI we will be introducing WPC products thought the year.

    Just a point of clarification:

    This is wonderful, Bill. Thank you for this important update.

    When I asked about other chargers, I meant to state that as, "Are there any other OTS Qi-Compliant chargers like the Energizer?"

    If you did that simple test with the Energizer, maybe you did it with others.

    The only other one I heard about is a Qi-Compliant charger from Maxell. But I cannot find an outlet for it.

    If you know of other OTS Qi-Compliant chargers at this time, let me know in a reply. Otherwise, I agree this thread is closed.

     

    Kind Regards,

    Michael A. Banak

    Michael,

    For LG wireless chargers you may check the nearest Verizon store.  Verizon offers wireless Qi compliant charging pad and back cover for LG Revolution phone.
