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)
