WattUp® wire-free charging reduces footprint and increases spatial flexibility

DA2210 and DA2223 feature four RF-to-DC receiver paths, allowing connection of 1 to 4 antennas dependent upon desired power and antenna area available. They are RF-to-DC wireless power receivers optimized for wireless charging applications. This includes applications such as wearables, fitness trackers, hearables, hearing aids, asset trackers, and other battery-powered electronics, where small implementation size and increased spatial freedom during charging provide advantages over coil-based charging solutions.

DA22102223 Block

Features

  • 4-Ports with 4 RF-to-DC rectifiers
  • Single port RF-to-DC efficiency of up to 74 % at +22 dBm input power
