This energy harvesting kit developer combines Energous’ radio frequency (RF) solution with e-peas’ power management IC technology to support at-a-distance wireless charging applications for smart buildings, industrial IoT sensors, retail electronic displays and more.
The WattUp Active Energy Harvesting transmitter incorporates the DA14682, DA4100, EN3921 and EN3913M devices. The DA4100 is a highly integrated system-on-chip (SoC) Wireless Power Transfer (WPT) transmitter IC, the EN3913M is a highly efficient GaN power amplifier (PA) controlled by the EN3921, while the DA14682 is a Bluetooth low energy 5.0 SoC with enhanced security and integrated FLASH memory. A lower power option is available with the DA3210 CMOS power amplifier.
On the receiver side, there are 3 input paths available to choose from based on use case, including discrete diode and DA2210 RF-to-DC implementations, which connect to the AEM30940 ambient energy manager chip and the DA14531, a size-optimized, ultra-low power Bluetooth low energy system-on-chip ideal for IoT devices.
