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.
