Reduce Footprint and Increase Spatial Flexibility in Wearables and Hearables with WattUp® Wire-Free Charging
The DA2210 RF-to-DC wireless power receiver is 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.
The DA2210 features 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. The DA2210 features external RF input matching for improved flexibility and RF-to-DC conversion efficiency. The device's DC outputs are internally clamped to limit the output voltage to within the range of most DC regulators.
Benefits
- RF/Antenna-based solution
- Smaller antenna than coil-based designs
- Improved spatial and orientation freedom
- Eliminates connectors and charging contacts
- Enables fully sealed waterproof design
Near Field WattUp System
The Near Field WattUp system is comprised of a WattUp wireless power transmitter (DA4100), a WattUp wireless power amplifier (DA3210), a WattUp wireless power receiver (DA2210 or DA2223), a DC regulator, a Li-ion/Li-poly battery charger and an optional Bluetooth® Low Energy communication link (DA14680*, DA14681* or DA14585) which supports battery status communication between the WattUp receiver and transmitter. The same link can be used to provide the user with full power management capabilities using the WattUp Application running on a Smartphone or tablet. Antennas are fabricated using low-cost PCB material, flexible PCB, or sheet metal.
特性
- External RF input matching for improved flexibility and RF-to-DC conversion efficiency.
- The device's DC outputs are internally clamped to limit the output voltage to within the range of most DC regulators.
