Energous Releases New Receiver IC Designed for Small Electronic Devices

Energous Corporation has released its DA2223 wireless receiver chip, which is the latest addition to its family of integrated circuits (ICs). At just 1.7mm x 1.4mm and less than 0.5 mm thick, the DA2223 4-port RF-to-DC wireless power chip is the smallest RF rectifier IC in the Energous technology portfolio.

Depending on the device power level, a complete WattUp wireless power receiver can be realized using a single DA2223 IC coupled with a matching circuit made from two standard discrete components and a tiny 2mm x 3mm antenna, which itself can be formed using simple printed circuit board tracking. Such a small form factor makes it ideal for use in small electronic devices where a coil-based wireless charging system is not practical.

Energous’ new DA2223 receiver IC:

  • Features four RF-to-DC rectifiers, allowing the connection of up to four antennas for optimal freedom-of-placement while charging, or the pairing of rectifier paths for increased power
  • Supports dual frequencies (915 MHz or 5.8 GHz)
  • Leverages the 12-pin WLCSP (Wafer Level Chip Scale Package), which offers customers flexibility in integration; max dimensions: 1.69 mm x 1.39 mm x 0.485 mm, 0.4 mm pitch
  • Complements the Energous portfolio of IC solutions, including the fully integrated WattUp power transmitter IC (DA4100) and the wireless power RF-to-DC receiver IC (DA2210)
