Wireless power ICs let smartphones wirelessly charge other devices
The company’s new WattShare wireless power ICs combine both receiver and transmitter capabilities, allowing smartphones, smartwatches, truly wireless ear buds and other devices to be wirelessly charged simply by placing them on top of a smartphone.
“WattShare-enabled smartphones will free users from carrying a variety of chargers and constantly looking for electrical outlets to keep their smartwatches, ear buds, and other devices charged,” says Christopher Stephens, general manager of IDT’s Wireless Power Division. “WattShare is the latest example of IDT’s continued advancement of the state-of-the-art in wireless charging technology and places the smartphone at the center of the wireless charging eco-system to ensure consumers can enjoy the most ‘untethered’ smartphone experience.”
The technology uses a single IC to receive and transmit power with an optimized single antenna design. WattShare enables smartphones to deliver up to 7 W of power when charging other devices, as well as to receive charges of 15 W or higher.
The technology has been developed and optimized over several years by IDT Labs. Several leading smartphone makers have already adopted WattShare, says the company, and have successfully created a wireless charging ecosystem allowing their customers to charge a friend’s phone or an accessory device.
