Wireless charging module accelerates development for Qi2 standard
Three companies have come together to develop a wireless charging module which can help OEMs developing the latest Qi wireless charging standard.
NuCurrent and Shanghai Amphenol Airwave have worked with NXP Semiconductors to develop the Qi2 Max wireless charging module.
“Qi2 Max offers OEMs a flexible, easy-to-integrate solution that accelerates product development while assuring compliance with the latest wireless charging standards,” said Jacob Babcock, CEO, NuCurrent. “Product designers can now confidently embrace the new standard introduced by the WPC [Wireless Power Consortium) in January, knowing that Qi2 Max ensures a safe and secure wireless charging experience,” he added.
The Qi2 Max uses NXP Semiconductor’s MWCT20D2VLH silicon with security capabilities which allows for on-chip authentication. These features help address the Consortium’s challenge of enforcing measures to eliminate counterfeit, non-Qi-certified devices.
“Authentication is one of the most important features of the Qi2 standard, providing the safety and security features needed to protect end users,” said Vaclav Halbich, Product Manager, NXP Semiconductors. “MWCT20D2VLH is a single-chip designed for Qi2 with that authentication capability already embedded. NXP silicon enablement and NuCurrent’s expertise allow Qi2 Max to minimise the engineering hours required from OEM customers,” he said.
In addition to increasing security and authentication requirements, Qi2 also requires more testing than Qi1, including the passing of stringent magnetics and Foreign Object Detection (FOD) tests. Ensuring tight manufacturing tolerances is critical to achieving certification.
“In preparation for the coming wave of Qi2 devices, Amphenol advanced its manufacturing processes to ensure uniformity throughout the markets who will adopt the standard,” observed Dan Gorsage, IoT business unit leader for Shanghai Amphenol Airwave.
Qi2 Max is now available for purchase and will be in products by autumn/fall 2023.
