The DA2210 is an RF-to-DC wireless power receiver optimized for wireless charging applications, such as wearables, fitness trackers, hearables, hearing aids, asset trackers, and other battery-powered electronics. It has four RF-to-DC receiver paths, allowing connection of 1 to 4 antennas depending on the desired power and antenna area availability. Antennas can be as small as 2 x 3 mm, typically used for hearing aids, and from 8 x 8 mm to 10 x 10 mm for wearables. Multiple antennas can be used to increase received power for devices with increased area, such as remote controls or battery banks.
