Other Parts Discussed in Thread: BQ51051B
I have a custom PCB based on TIDA-00623 using same coil from the reference: WE 760308111, which was also recommended to me directly by WE to pair with the coil I use on my RX side.
In initial testing, the implementation appears to function normally. It recognizes devices placed on the coil, the LED_A (using LED Control Option 1, 24.9kohm) blinks slow indicating power transfer, and I can measure just over 6VAC moving through the coil.
When placing my iPhone on the coil, it recognizes the charger and indicates "charging" however the battery continues to discharge. When placing my custom RX device based on BQ51051B on the coil, same behavior -- and I can see my custom charge status indicators on the RX side are unresponsive.
Anyone have any idea why TIDA-00623 based design would indicate power transfer but no power is received on the RX side, only apparently communication?
