Can the BQ500412 be used to charge the BQ51013A or do I have to use the BQ500210? One other question as well...

Other Parts Discussed in Thread: BQ500210, BQ51013A, BQ500412, BQ51013B

Hello,

I have begun work for a wireless charging station that needs to charge an accessory that uses the BQ51013A receiver. The BQ51013A is WPC v1.0 compliant and the datasheet for this part mentions using it with the BQ500210 (also WPC v1.0 compliant).

Is it okay if I use the BQ500412 in a 3-coil configuration to charge this accessory? The BQ500412 is a 12V solution (instead of the 5V of the BQ500210), but I don't think this will be an issue because the datasheet for the BQ51013A can take a max input voltage of 20V. I am concerned that they might not communicate because one of them is WPC v1.0 and the other is WPC v1.1.

My other question is this: is it possible to swap a BQ51013B in for the BQ51013A? Using the BQ51013B would alleviate all of my compatibility concerns with the BQ500412, but, it might require a redesign of the board. Does the BQ51013A and the BQ51013B use the same external circuitry or are there differences?

Thanks,

Seth Berggren

  • Hello Seth,


    Since all new WPC versions have to be downwards compatible, the BQ51013A and BQ500412 will work fine together except that the Foreign Object Detection feature is not present in the 13A.

    You can substitute a 13B, which enables FOD but then tuning will be required. Tuning is done with a GUI which is available in the product folder of the device and external hardware which is described in the User Guide. The User Guide is available within the GUI.

    Best regards,
