The approval by the FCC of the Mid Field WattUp transmitter reference design from Energous was the final step in the end-to-end chain of devices, says Dialog, which has a strategic investment in the company. The additional devices will start shipping this quarter.
The availability of a complete chip roadmap paves the way for a fundamental shift in the way consumers charge many of their portable electronics and Internet of Things (IoT) devices, including smartphones, wearables and hearables, it says. “This landmark FCC approval further strengthens Dialog’s position as both a strategic investor and worldwide exclusive supplier of Energous WattUp technology,” said Mark Tyndall, Senior Vice President Corporate Development & Strategy at Dialog. “It proves the era of wireless charging 2.0 has arrived as power-at-a-distance wireless charging becomes a reality with the delivery of a complete system chipset.”
Dialog has already launched and sampled a WattUp wireless power transmitter System-on-Chip (SoC), the DA4100, alongside the first WattUp RF-to-DC receiver ICs, the DA2200 and DA2210. These chips not only enable RF-based, Near Field (contact based) wireless charging but are also fundamental to the now certified Over-the-Air, Power-at-a-Distance Wireless Charging system. As a result, Dialog is accelerating the next phase in WattUp chip set qualification by adding the critical DA1210 Beamforming IC and the DA3210 Power Amplifier (PA) IC, needed to complete the chipset for the Power-at-a-Distance transmitter system.
The FCC is the first time equipment certification has been awarded to any device that charges wirelessly at a distance, and operates under Part 18 of the FCC’s rules. The FCC’s Part 18 rules permit higher-power operations than are permitted under the Part 15 rules that have been used to approve other at a distance charging devices.
“With the very recent FCC certification of our WattUp Mid Field charging-at-a-distance transmitter, having an established semiconductor manufacturing partner like Dialog to bring the technology to fruition is a strong market advantage for Energous,” said Stephen R. Rizzone, President and CEO of Energous. “We see this as an incredible opportunity to drive the wireless charging industry forward at an accelerated pace.”
Dialog will be sampling the DA1210 beamforming IC and DA3210 PA to lead customers this quarter and will provide complete system solutions for both Near Field and Power-at-a-Distance Wireless Charging by combining the full range of WattUp ICs with its SmartBond Bluetooth low energy, AC-DC and Power Management chips. Dialog is also working with Energous to commercialize WattUp high power Near Field systems through the use of high efficiency GaN ICs which provide sufficient power to charge smartphones and other such consumer devices.
