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 existing products, while maintaining a small footprint.
In addition, a receiver side I2C interfacecompatible 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 just 2.4×3.67×0.5mm, 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 1.7A and adjustable output voltage settings of 5-14V, the receiver is compatible with Toshiba’s 5W transmitter IC TB6865AFG, as well as with other 15W wireless charging transmitters complying with the Qi v1.2 standard.
