The TC7766WBG, which has been designed for use in mobile devices such as smartphones, tablets and a range of mobile industrial devices, 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 existing products, while maintaining a small footprint.

In addition, 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.

Housed in a WCSP28 package measuring 2.4 mm by 3.67 mm by 0.5 mm, the TC7766WBG features a host of 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 cutting-edge CD-0.13 process.

With a maximum output current of 1.7 A and adjustable output voltage settings of 5V-14V, the new receiver is compatible with Toshiba’s 5 W transmitter IC TB6865AFG, as well as with other 15 W wireless charging transmitters complying with the Qi v1.2 standard.
