LONDON – Texas Instruments has introduced the bq500210, an IC that controls and transfers wireless power for contactless chargers compliant with the Qi standard from the Wireless Power Consortium.
The chip includes an analyzer that examines the efficiency of energy transfer and chokes back transfers as the target device becomes charged and to protect the transmitter and receivers from excessive power loss and heat. The chip also performs metal object detection to provide protection from power transfer to extraneous metal objects. It also includes overload and over-temperature protection circuitry.
It comes in a 48-pin QFN package and is priced at $4.50 in quantities of 1,000 units. It is compatible with the available bq51013 or bq51011 receivers.

This IC should also include BlueTooth functionality to communicates with device being charged. This way it can be made more efficient and also helps consumer of different status.

Why not just modulate data onto the AC?

You can very easily integrate a couple of IC´s into a product. One for Bluetooth and one for the wireless power management.
Perhaps integrating both under a single chip would result in noise problems.

This is revolutionary chip, just wondering if this is first of kind chip or do we have this chip available already from other manufacturers ?

What is the range over which such wireless transfer can happen without excessive power loss to the environment? and what happens when there is intermittent interference between the charged and the charging stations?

This is a chip that Nicola Tesla would´ve loved. He wanted to distribute energy through air. Wirelessly. Perhaps he was the first "Open source" advocate.
Aren´t we seeing too much wireless lately? Anyone saw Jhony Mnemonic? Lucky for the business that RF radiation hasn´t been proved to harm our bodies.
