The TC7766WBG enables fast wireless charging, with charging times similar to, and in some cases less than, wired charging. It accomplishes this by increasing the power reception capability by a factor of three compared to some existing products, while maintaining a small footprint. A receiver side I ²C interface compatible host controller can exchange information with a compatible transmitter to enable user-notification of wireless charging status via the mobile device display.
In a WCSP28 package measuring 2.4 x 3.67.x by 0.5mm, the TC7766WBG incorporates multiple protection functions as well as all the rectifier circuits and controllers needed to construct a standalone wireless power transfer Rx system. The device is constructed using Toshiba?s original CD-0.13 process.
With a maximum output current of 1.7A and adjustable output voltage settings of 5V-14V, the receiver is compatible with Toshiba's TB6865AFG 5W transmitter IC, as well as with other 15W wireless charging transmitters complying with the Qi v1.2 standard.
