I am a newbee to wireless charging and I seriously need help. I have never worked on this kinda of projects and any help or feedback would be greatly appreciated. I do have a 4.2 V lit-Ion Battery that I need to transmit charge through air to the receiver side. I seriously dont know what are the options out there, specially with TI. First question is that would these transmitter chips also know (feedback) that the receiving battery side is fully charged, thus to shut down the continuous charging process? I was reading online but it seems that there is two chips required for the transmitter side to work. One is the BQ50002A and the second chip would be the BQ500511A. Is there a one chip solution for this matter? Is there any easy chip that could be simpler to use?
Secondly, I'm looking for a battery charging chip that would charge a 3.7 volt lit-Ion battery that would also check the battery level to shutoff if the battery is fully charged.
Thanks in Advance.

Many thanks for your fast response and sorry for my late response. All of the information above is the details that I was looking for. I have another question, So I have this switch that when it gets activated the charging would start. I assume the the BQ50002A and the BQ500511A would automatically stop the wireless charging when the battery pack hits the 100% mark. By thinking that the chips control (BQ50002A and the BQ500511A) the wireless charging I need a logic system that when I hit the switch two times (at least 1 minute a part) the charging logic stops completely. Any recommendations? Also if the switch is before the BQ24040 would I need a switch filter(regulator). Does the BQ24040 have an internal switch bouncer to prevent any noising signal generated from the switch?

Again thanks for the response but I do have more questions here. I have looked at the BQ51050b, This is a Wireless charging Receiver, I need a solution that would be acting as a Transmitter and a receiver in one chip, to read the current amount of the call phone battery that is charging and then depending on what the amount is then it will either stop the charging or would add more charge to make the battery pack fully charged. BQ50002 and the BQ500511 are Transmitting but they don't read. I only have one coil that could be receiving and Transmitting, but with the chips provided I don't have a clear understanding of how to make this a transmitting and receiving logic. Could you please guild me through this process.
Also as for the BQ24040:
Do you guy have a regulator that would have a 0-5 volt input and outputs a clean 4 volts?
Lastly, Does TI have a 2A or greater single Iit-Ion Battery charger?
