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
