Energous Announces Availability of Wireless Charging Receiver Chip for Wearables

Energous announced a receiver chip Tuesday targeted to earbuds, hearing aids and wearables. The DA2223, a four-port RF-to-DC wireless power chip, can be delivered in a single integrated circuit coupled with a matching circuit made from two discrete components and a 2mm x 3mm antenna, making it applicable for small electronic devices "where a coil-based wireless charging system is not practical,” said the company. The chip is produced by Dialog Semiconductor, which has a stake in the wireless charging company.
