BQ51013B: bi-directional communication

HS FAE Germany

Part Number: BQ51013B
Other Parts Discussed in Thread: BQ51021, BQ500212A

Hello,
is there a possibility of a bi-directional communication with the bq51013b? Or do I need an additional NFC IC for it? If yes, do you have a reference design?

Hello Holger
No the BQ51013B does not have the option for di-directional communication.
No reference designs to support this.
Sorry

can I use the uni-directional communication from the receiver to transmitter also for application specific data/commands? Or is this close to WPC protocol commands?

I want to use the charging coils also for NFC communications.

Hello

The BQ51021 has I2C interface and the option to send data to the transmitter. For this approach you will also need an transmitter that can support this function. The BQ500212A has I2C.

Sorry do not have info on coil that will act as NFC and Charging.
