Dialog Semiconductor Announces Investment in Energous Corp. to Accelerate Wireless Charging Adoption



Dialog Semiconductor plc, a provider of integrated power management, AC/DC power conversion, solid state lighting (SSL) and Bluetooth low energy (LE) technology, has invested in Energous Corp, the developer of WattUp, a wire-free charging technology. Dialog invested$10 million in Energous to become the exclusive component supplier of the WattUp integrated circuits (ICs).
Energous’ WattUp technology sends energy safely through the air using radio frequencies, delivering scalable power in a similar way to a Wi-Fi router. WattUp delivers power at a distance, to multiple devices, in any orientation.
The partnership combines Energous’ uncoupled wireless charging technology and Dialog’s power saving technologies. Energous’ WattUp technology uses Dialog’s SmartBond(R) 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 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.
