Energous And Dialog Semiconductor’s New Wireless Charging Module Provides Speed for an Array of Applications

September 07, 2020 by Antonio Anzaldua Jr.

Energous Corporation announced a new module that integrates components provided by Dialog Semiconductor in a strategic partnership to create a faster wireless charging solution. for smart speakers, medical devices, laptops, fitness bands, and more mobile devices.

The charging solution works for smart speakers, medical devices, laptops, fitness bands, and more mobile devices. 

Founder Michael Leabman launched Energous in 2013 with the goal of creating a wireless charging solution that could be used universally across a spectrum of applications.

In 2016, Energous Corporation began a strategic partnership with Dialog Semiconductor along with an investment of over $25 Million. At the beginning of August 2020,  Energous announced its EN7410M wireless charging technology that combines transmitter IC and power amplifiers into a smaller footprint to expand and expedite the adoption of wireless charging for mobile devices, hearing aids, and smart speakers.

 

Dialog’s Receiver and Transmitter Devices

Dialog’s investment was only one part of the strategic partnership developed with Energous. It allowed for the integration of various ICs to be used for improving the wireless charging solution, WattUp.

Dialog Semiconductor’s DA2210 and DA2223 feature four RF-to-DC receiver paths, allowing connection of 1 to 4 antennas dependent upon desired power and antenna are 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 an increased area, such as remote controls or battery banks.

The WattUp transmitter utilizes Dialog’s DA4100 is a highly integrated RF transmitter System-on-Chip designed to provide optimal charging. Featuring a power management solution to deliver a complete WattUp transmitter system. The WattUp transmitter system includes an ARM Cortex processor, RAM, ROM, crystal oscillator, low profile oscillator, clock divider, RF converter, and variable gain amplifier.

Dialog’s DA3210 is a high power, high-efficiency RF power amplifier that, together with the WattUp wireless power transmitter DA4100, is designed to provide optimal charging of WattUp receiver devices. It completes the Near Field WattUp transmitter. It features a single channel RF power amplifier, input and output power detectors that enable closed-loop power control, and an integrated temperature sensor.

 

The EN7410M

Energous has designed the EN7410M module which combines Dialog’s DA4100 transmitter and DA3210 RF power amplifier. This module can be designed into many different sized electronic devices in the medical, industrial, retail, and automotive industries.

 

The EN7410 charging module features:

  • 31 mm by 16 mm footprint
  • Low-cost PCB technology
  • 1W maximum power output
  • On-board harmonic filter
  • RF output via pin or on-board U.FL connector
  • Bootable UART Host interface for connectivity
  • I2C master for peripheral control

 

Dialog’s DA4100 and DA3210 are in series with a harmonic filter to prevent unwanted distortion for WattUp’s transmitter. This allows for frequencies to transmit to Dialog’s RF-to-DC wireless power receivers, DA2210 and DA2223.

 

This module allows for wireless charging at close proximity. Energous and Dialog hope this solution will replace the standard USB charging experience.

President and CEO of Energous, Stephen R. Rizzone discussed how the new module would improve the WattUp charging solution and said, “By making it easier to integrate the WattUp technology, the module will significantly reduce the effort and time required to integrate it into end-user devices, thereby accelerating our customers’ product cycles and reducing the time and cost to bring these devices to market.”

 

The Grepow Battery

In addition to its partnership with Dialog Semiconductor, Energous Corporation has also begun working with one of the world’s leading battery manufacturers in China, Grepow Battery.

 

Energous’s near-field charging solution allows for a few millimeters of distance while their far-field charging solution allows for up to 15ft.

Energous and Grepow Battery plan to develop batteries that are charged by WattUp for use in electronic devices across commercial, industrial, and medical industries. 

Peter Liu, CEO at Grepow Battery shared his enthusiasm toward the new partnership with Energous

“We are thrilled to work with Energous Corporation on next-generation batteries with their award-winning WattUp RF-based wireless charging technology,” Liu said.
