WiTricity introduces the WT8800 wireless charging controller that incorporates its magnetic resonance technology that makes it possible for consumer brands to build wirelessly-powered products of the future. The controller accelerates consumer adoption of wireless charging and targets wearables, smartphones, and laptops.
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 ASIC helps consumer brands to easily incorporate the patented wireless power technology into their products and deliver fast, flexible charging.
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 W. The mixed signal SoC architecture integrates the complete analog and digital controller functions of a power transmitter unit 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 using the WT8800, are available for up to 30 W of delivered power. These designs are being leveraged by consumer product companies and their ODM manufacturers licensed by WiTricity.
