The EMC vendor has requested for FCC grant conditions and FCC IDs. Does TI have such information for BQ51003?
Part Number: BQ51003 Hi,
We are trying to design a wireless charger using BQ51003.
I understand how to calculate C1 and C2 on Rx resonant circuit but I don't know how to measure resonant frequency and adjust an actual sample.
How did you measure resonant…

Part Number: BQ51003 Other Parts Discussed in Thread: BQ500212A , TEST Hi,
We are using the BQ51003 in our design as a QI receiver. In order to validate the solution with a prototype we would need a EVM of a Qi transmitter, but from what I have seen so…
Hi Anthony,
I tried again, added between the coil and the battery 38M3010AA1212 (1934-1086-ND Digikey) ferrite sheet the size of the battery. Peeled off the adhesive, and attached to the battery surface.
Measured the Ls' once more and the calculations…
