BQ500215: can't support 10W.

Part Number: BQ500215

Hi,

I found some of my product BQ500215 can't support 10W. I remove FP_DECAY or FP_RES resistor it will be normal work.

1. What's problem need to consider when I remove FP_DECAY and FP_RES resistor?

Hello

The two resistors are part of an FOD ping circuit that try to detect a foreign object on the charging pad due to change in the Q of the circuit.

Has the TX coil changed or does the RX have a lot of metal in it?
