Freescale is taking a big step towards bringing wireless charging to laptops and other gadgets, with a new wireless product set to hit the merket early next year. The 15 W Qi-compliant wireless charging solutionis delivering 3x the power of common 5 W charging solutions, providing 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 4000 mAh 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 15 W 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).

This targeted solution includes two 15 W ICs: the WPR1516 receiver chip and accompanying MWCT1012 transmitter chip. Developers can get to production using available corresponding firmware libraries, which provide the core functionality required to implement 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 tailored end-product.

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.
