Dialog Semiconductor and Energous to Accelerate Wireless Charging Adoption

Dialog Semiconductor has announced a strategic investment in Energous Corporation, the developer of WattUp, a revolutionary wire-free charging technology that provides over-the-air power at a distance. Dialog has agreed to make a $10 million investment in Energous and become the exclusive component supplier of the WattUp integrated circuits (ICs), while Energous is able to leverage Dialog’s broad sales and distribution channels to accelerate market adoption.

Energous’ WattUp technology provides a unique and more extensive wireless charging experience compared to traditional coil-based technologies. By sending energy safely through the air using radio frequencies, WattUp is able to deliver intelligent, scalable power in a similar way to a Wi-Fi router. It differs from inductive or resonant wireless charging systems in that it delivers power at a distance, to multiple devices, in any orientation, resulting in a wire-free experience that has the ability to transform the way consumers and industries charge and power electronic devices at home, in the office, in the car and beyond.

The partnership combines Energous’ uncoupled wireless charging technology and Dialog’s power saving technologies to drive market expansion. The WattUp technology uses Dialog’s SmartBond Bluetooth low energy solution as the out-of-band communications channel between the wireless transmitter and receiver. Dialog’s power management technology is then used to distribute power from the WattUp receiver IC to the rest of the device while Dialog’s AC/DC Rapid ChargeTM power conversion technology efficiently delivers power to the wireless transmitter.

WattUp uses small form factor antennas that are formed using the existing device’s printed circuit board, removing the need for larger, more expensive coils used in competing solutions today. This enables broader adoption of wireless charging in a larger range of battery-powered devices, such as smartphones, tablets, Internet of Things (IoT) devices, small form factor wearables, and Virtual Reality (VR)/Augmented Reality (AR) devices. Accelerated sales growth will be achieved by leveraging Dialog’s strength in delivering volume and tier one customer access.

Energous’ WattUp technology can be thought of as wireless charging 2.0, and delivers a wireless charging experience that is much closer to what consumers desire by charging devices close up and at a distance, while in use and without compromising product design or adding excessive cost.

The strategic investment includes positive tactical and strategic implications that will aggressively speed up customer adoption of WattUp-enabled products and streamline chip production. Benefits of the agreement include joint marketing and sales operations, including access to Dialog’s channel partners and access to Dialog’s customer base to accelerate the adoption of WattUp in smartphone, automotive and emerging IoT applications.

Dialog will be showcasing Energous’ WattUp technology at CES from January 5 to 8, 2017 in its private demo suite with lead customers expected to be in production from first half 2017.
