BQ51025: Tooling, Software, CE/FCC certification

Dennis Dekker
Prodigy 10 points
Part Number: BQ51025
Other Parts Discussed in Thread: BQ500215, , BQ51050B, BQ51003

Hello TI,

We have a question about the BQ51025 and BQ500215 wireless power receiver and transmitter chips.
We use these parts in our product and are currently working on CE / FCC certification for this product.

These parts with Qi are not FCC certified and therefore additional Radio Frequency testing is necessary.
Our test laboratory want to “force” them in specific modes during RF testing.
- Mode 1: charger* in stand-by (idle mode)
- Mode 2: Communication before charging, adjustment charging mode / position
- Mode 3 and Mode 4: Communication during charging and Charging (tested together)
(*we charge a device using wireless power)

Is it possible the configure the chips in the modes described above, has TI experience with CE/ FCC certification?
Is there documentation or a test tool / firmware available for these kind of configurations, or if we have to create such (test) tooling / firmware ourselves.
The BQ51025 receiver has a I2C port available for a host interface, so something is maybe possible.
The BQ500215 does not have an interface available, how can it be approached?

Thanks in advance for your help.
Kind regards,

    Hello Dennis,

    We are currently only supporting a limited number of  <5W RX devices including bq51003, bq510013b, bq51050b. 10W receivers and all transmitters from TI have been made NRND.

    Best regards,

    Nick

    Hello Nick,

    Thank you for the replay.
    This is not the answer we expected from TI.
    We know the parts are NRND, but at this moment we can’t afford a large redesign so we have to continue.

    You mention all 10W receivers and transmitters are NRND, what is the reason for this?

    According to our test house, the TI (WPT) Wireless power transmission systems are in scope of the ETSI EN 303 417 Harmonised European Standard. ETSI EN 303 417

    In our opinion the certification for a 5W or 10W doesn’t really make any difference.
    I take a look at your suggested BQ51003 5W receiver, this parts doesn’t have a I2C host interface.
    So if we had used these, the same questions arise about certification.

    It would be nice if TI could help us anyway.

    Kind regards,
    Dennis

    Hi Dennis

    Sorry but we do not have control software that can put the BQ51025 / BQ500215 system into the above modes. Some possible options are below but would require a test version of the RX (BQ51025).

    Mode 1: charger* in stand-by (idle mode) --- A possible solution is to send Charge Complete to TX.  On RX pull TS/CTRL Pin high.
    Mode 2: Communication before charging, adjustment charging mode / position--TX does not support this option.
    Mode 3 and Mode 4: Communication during charging and Charging (tested together) -- Normal power transfer into resistive load on RX

    The BQ51025 / BQ500215 10W system was a proprietary design to fill a gap in the portfolio until the 15W Qi systems  were released.  A business decision was made to not continue with wireless power development and NRND transmitters and higher power systems.

    Hello Bill,

    Thanks for your investigation and reply.
    We have been in contact with our EMC test house and they will investigate how to proceed the CE/FCC certification of the WPT, without software / test modes. If any addition information is needed, we let you know.

    Best regards,
    Dennis

    Hi Bill,

    We had contact with our EMC test house.
    They ask for test results/ reports regarding ETSI EN 303 417 (Wireless power transmission systems).
    Could you provide us this documentation?

    Thanks and regards,

    Dennis

    Hi Dennis

    We have run EMI and EMC test on the BQ51025 / BQ500215 evaluation boards but not EN 303 XXX.
