DA2223数据手册Renesas中文资料规格书

描述 Description

DA2210 and DA2223 are RF-to-DC wireless power receivers optimized for wireless charging 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.\r
\r
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. Antennas can be small enough to fit into in-the-ear hearing aids. Multiple antennas can be used to increase received power for devices with increased area, such as remote controls or battery banks. Both DA2210 and DA2223 features external RF input matching for improved flexibility and RF-to-DC conversion efficiency. The device DC- outputs are internally clamped to limit the output voltage to within the range of most DC regulators. With a form factor smaller than DA2210, DA2223 is ideal for use in very small electronic devices, thus offering further flexibility in integration.
