WiTricity Unveils Resonance-Based Wireless Charging Controller


WiTricity, an industry pioneer in wireless power transfer, has announced the WT8800 Wireless Charging Controller. The WT8800 controller incorporates WiTricity’s magnetic resonance technology, and unique proprietary know how, making it possible for consumer brands to build wirelessly-powered products for the future. The WT8800 controller will accelerate consumer adoption of wireless charging by enabling delightful user experiences across multiple consumer electronics markets including wearables, smartphones, laptops and others.

Consumer demand is growing for wireless charging experiences that are flexible and efficient. Solutions currently on the market that require precise alignment between device and power source are not meeting that demand. WiTricity’s magnetic resonance technology enables spatial freedom, the ability to charge through materials and the charging of multiple devices with the same source – key differentiators for the desired end-user experience. Working at the same speed as wired charging, WiTricity lets consumers power up in a fast, natural way.

The WT8800 controller brings its magnetic resonance technology to products, enabling wireless power transmitters with scalable output power, ranging from a few Watts to 100 Watts to meet varying requirements of wearables, smartphones, laptops and other devices. The mixed signal System on Chip (SoC) architecture integrates the complete analog and digital controller functions of a Power Transmitter Unit (PTU) compliant with the AirFuel Alliance's Resonant Wireless Charging Standard, ensuring ecosystem compatibility. The specific functions integrated include functionality to control the DC bus voltage, power amplifier and user interface. It also incorporates all appropriate safety features including current, voltage and temperature monitoring. 

AirFuel-certified Wireless Power Transmitter system reference designs utilizing the WT8800 are available for up to 30 Watts of delivered power. These designs are being leveraged by consumer product companies and their ODM manufacturers licensed by WiTricity. Customization for other power levels is contemplated in the design.

WiTricity is offering the WT8800 controller, along with a robust library of reference designs, to help global brands accelerate their introduction of this game-changing consumer technology.

Demonstrations of wireless power solutions based upon the WT8800 controller will be shown at the 2017 International Consumer Electronics Show (CES) in Las Vegas, including at the AirFuel Alliance exhibit booth (Tech West, Sands Expo, Level 2, Halls A-D, booth #41139).
