15W wireless power receiver IC is Qi v1.2 compliant
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 I²C 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.
