BQ51013B: Communicate battery status

Part Number: BQ51013B

Hi,

Im a final year undergraduate.

we are trying to build a wireless charger for implantable devices. Transferring the power and the charging part is almost done. Now we are focused on to communicate battery states to the surface. in BQ51013 there is backscatter communication mode, but its not free to use for the user. Is their any possibility to transmit users data through this Ic. If not Is their any WPC IC which have a spare communication channel.

Thank you. 

  • Hi Kasun
    The bq51013B does not have RX to TX data transfer. Another device the bq51021 has I2C bus capability that can be used for data transfer.

    sir,
    Thank you very much for guiding me through the correct Rx ic. can you suggest me a TX ic which has the capability to receive proprietary packet data and a method to take a output according to the received data packet.    
    Thank you.

    Take a look at the bq500212A it will support proprietary packets.

    Hi,
    Thank you very much for guiding me. I hope to use bq27542-G1 battery fuel gauge to determine the SOC. Then write SOC data to the registers of bq51021, through I2C communication. Do you think is it a possible thing to do? If yes can you suggest a device to serve as a master device of I2C communication. I want to reduce the dimensions. so i want a master device as small as possible.
    thank you.
