Renesas Electronics Corporation has partnered with Qualcomm Technologies to accelerate the widespread adoption of wireless charging for smartphones.
Reneses is investing in 30W wireless charging capabilities for mid-range smartphones powered by the latest Qualcomm Snapdragon 780G 5G Mobile Platform.
This is the second reference design collaboration for high-power wireless charging smartphones for the two companies. The first solution, designed for flagship devices, is now commercial sampling.
This final phase is an important step that extends the collaboration of the two companies to introduce highly integrated, advanced wireless power functions as standard in 5G smartphones, from flagship to mainstream devices.
Qualcomm Technologies 5G mobile reference designs provide turnkey solutions intended to enable smartphone OEMs to implement fast and cost-effective fast wireless charging on flagship and mid-range smartphones, with Multi-Time Programmability (MTP) and OTA updates to simplify software development and Qi certification process.
According to the company, the Renesas solution offers the highest integration with over 85% end-to-end system efficiency, to extend the reach of wireless power technology to a wider range of customers and to simplify the process of adding wireless charging.
Amit Bavisi, vice president and general manager of mobility infrastructure and IoT energy company Renesas Wireless Power Group, said, “We are delighted to expand our partnership with Qualcomm Technologies as part of our journey to develop advanced wireless charging solutions and open up reliable wireless power access for mass adoption.
“The combination of our highly integrated 30W technology and Qualcomm Technologies’ advanced 5G technology is intended to provide OEMs with a turnkey solution with the best wireless charging capabilities to make it easier to deliver fast wireless charging technology to the industry. next-generation middle class. reach smartphones. “
Ev Roach, VP of product development at Qualcomm Technologies, says, “In our partnership with Renesas, we focus on delivering more seamless, wireless user experiences.
“In partnership with Renesas, we aim to provide turnkey fast wireless charging solutions for common mobile devices.”
The Renesas P9412 Wireless Power Receiver is a 30W power receiver with a high voltage integrated capacitor divider, which provides greater energy efficiency with 40% reduction in solution size compared to conventional solutions, and frees up PCB space for customers to perform other functions on the company states. .
For a safe and fast charging experience, a custom high-power protocol is embedded in the device firmware, allowing the system to verify power transfer beyond the 15W defined by the WPC EPP standard.
Renesas Wattshare technology allows the mobile device to become a power source and wirelessly charge accessories in the ecosystem, such as earbuds and smart watches.
Renesas specializes in wireless power solutions for both the Power Receivers (PRx) used in smartphones and other applications, and the Power Transmitters (PTx) used in charging pads and car-in-car applications.
