BQ500215: Wireless transmitter communication

Part Number: BQ500215

Hi,

I am a university final year student. I am using this IC for wireless power transmitting circuit. I want to know that is there a possibility to take the demodulation of the signal to the outside?

Thank you.

Regards,

Janith Chamikara.

  • Hi Janith
    I am not sure what the plan would be to take the "demodulation of the signal to the outside" could you clarify.
    1.) A parallel demodulation ckt can be set up outside the IC to read data going RX to TX. But this could not be used by the TX IC.
    2.) The IC does not output a raw bit pattern of the demodulated signal.

    Sir,
    I am a final year student in the university. As my project, I am building a wireless charging implantable device. From the receiver, I am trying to send signals other than charging related data. I am trying to change the AM signal, the receiver generating to take battery states also. If I could send the signal from the receiver , is there a way to demodulate that signal from the TX side.
    Thank you.

    Hi Janith
    For data transfer RX to TX it may be possible to used the Proprietary Packet option of the bq51021 Receiver to send info to bq500215 TX. This would require I2C communications with both RX and TX.

    Sir,

    Can u explain me how to set up parallel demodulation circuit for the BQ500215 IC.

  • In reply to Janith Chamikara:

    This will be a difficult design and I do not recommend it.
    Have you reviewed the bq51020 and can that possible meet your requirements?
