NuCurrent, the global authority in wireless power systems, and Shanghai Amphenol Airwave Communication Electronics Co., Ltd, an operation within Amphenol Corporation, working with NXP Semiconductors, a leader in wireless charging transmitter silicon, have developed the Qi2 Max wireless charging module for consumer, industrial and medical OEMs. This offering was brought to market in response to the urgent industry-wide need to shift compliance towards the new Qi2 standard.
“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 in January, knowing that Qi2 Max ensures a safe and secure wireless charging experience.”
Inside Qi2 Max is NXP Semiconductor’s MWCT20D2VLH silicon with security capabilities which allows for on-chip authentication. These features help address the Wireless Power Consortium’s (WPC) challenge of enforcing measures to eliminate counterfeit, non-Qi-Certified devices. End-users will ultimately enjoy a safer, more secure wireless charging experience across a broader range of 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 solution designed for Qi2 with that authentication capability already embedded. NXP silicon enablement and NuCurrent’s expertise allow Qi2 Max to minimize the engineering hours required from OEM customers.”
In addition to increasing security and authentication requirements, Qi2 also requires more testing (compared to Qi1), including the passing of stringent magnetics and Foreign Object Detection (FOD) tests. Ensuring tight manufacturing tolerances is critical to achieving certification.
“The investment in developing a Qi Certified device can all fall apart if manufacturing processes are not capable,” said Dan Gorsage, IOT Business Unit Leader for Shanghai Amphenol Airwave. “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.”
