Dialog Semicondcutor recently announced it will be the exclusive supplier of Energous Corp.’s WattUp RF-based wireless charging ICs. As part of the partnership, Dialog will make a $10 million investment in Energous and work to help drive broader adoption of wireless charging in products such as smartphones, IoT devices, wearables, and more.
The partnership combines Energous’s uncoupled wireless charging technology and Dialog’s power-saving technologies. 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 then distributes power from the WattUp receiver IC to the rest of the device. Dialog’s AC/DC Rapid Charge power conversion technology delivers power to the wireless transmitter.
