Bringing customers one step closer to the wireless Internet of Tomorrow, Freescale Semiconductor today extended its wireless charging portfolio by introducing the industry’s first 15W Qi-compliant wireless charging solution. The solution paves the way for ultra-fast wireless recharging for a variety of larger mobile devices including tablets, large-screen smart phones and portable industrial and medical equipment.
Delivering 3x the power of common 5W charging solutions, Freescale’s 15W wireless offering provides efficient charging of larger form factor devices with higher capacity batteries, while enabling faster charging of smaller form factor devices by delivering higher power. For example, a typical tablet with a 4000mAh battery might take over eight hours to charge from a standard USB port, while Freescale’s solution could reduce this charge time dramatically to just a few hours.
Freescale’s new 15W portfolio includes transmit and receive ICs complemented with flexible enablement technologies to speed the creation of wireless charging systems. Additionally, the new solution supports several major industry standards, including the Wireless Power Consortium (WPC) and the 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 15W solution is engineered to address these evolving market requirements, while helping to streamline product development and unleash design creativity.”
This targeted solution includes two 15W ICs: the WPR1516 receiver chip and accompanying MWCT1012 transmitter chip. Developers can get to production quickly by using available corresponding firmware libraries, which provide the core functionality required to implement state-of-the-art wireless charging systems. The solution also includes an advanced application programming interface that can be utilized to modify or adjust library functionality, allowing for the addition of custom application code and a highly tailored and differentiated end-product.
Extensive development support
Freescale’s newest total system solution includes a production-ready reference design and evaluation boards for optimized performance and fast time to market. To support the WPR1516 receiver IC, Freescale provides two evaluation board options for different output power topologies, WPR1500-LDO and WPR1500-BUCK. The MWCT1012 transmit controller IC is supported with the WCT-15W1COILTX reference design.
Availability
Freescale’s 15 W wireless charging solution is planned for availability in Q1 2015.
