Freescale Semiconductor announce 15W wireless charging solution
While wireless charging is a great way to charge devices without using cables, it is very slow. Even the traditional USB chargers now charge much faster than these wireless charging devices. Well, not any more. Freescale Semiconductor has announced world’s first 15W Qi-compliant wireless charging solution. Compared to current generation wireless charging solutions, this one will be up to three times faster. And this is much needed for devices with huge batteries like phablets and tablets. The new solution will support major standards like wireless power consortium (WPC) and power matters alliance (PMA).
“Today’s mobile products offer a broader range of features, functionality and form factors than ever before, requiring developers of wireless charging systems to accommodate larger batteries and enable faster recharge speeds,” said Denis Cabrol, director of global marketing and business development for Freescale’s MCU group. “Freescale’s industry-first 15 W solution is engineered to address these evolving market requirements, while helping to streamline product development and unleash design creativity.”
The new solution comprises of WPR1516 receiver chip and MWCT1012 transmitter chip. By using firmware libraries and APIs provided with these chips, device makers can bring products out in very less time. The images above shows circuit diagrams for these two chips. Freescale is planning to make the new wireless charging solution in Q1 2015.
