Freescale Semiconductor has introduced a range of fully programmable wireless charging ICs and reference designs which target automotive and consumer applications. The new Wireless Power Consortium (WPC) Qi-certified transmit controller ICs and reference designs are fully qualified and are now available. As feature-rich, power-hungry mobile devices become more popular with consumers, new wireless charging system deployments in offices, hotels, airports and other public spaces are driving demand for highly flexible solutions that allow for more innovative, highly customisable implementations.
Freescale is looking to address these needs by providing differentiated wireless charging solutions to meet the needs of both automotive and consumer applications.
Unlike competing products that tend to restrict customisation, Freescale’s new offerings are intended to support design innovation and enable the rapid development of differentiated wireless charging systems. Flexibility is provided through a programming interface that places maximum control of the end-solution in the product developer’s hands.
“Current solutions in the market offer very little customisation or flexibility,” said Denis Cabrol, director of global marketing and business development for Freescale’s MCU group. “Freescale’s programmable wireless charging solutions offer ground breaking design flexibility, combining silicon and software to give systems designers advanced technology to help redefine mobility.”
The company’s customisable automotive solution consists of a Qi-certified transmit controller IC and accompanying reference design. The programming interface allows systems designers to address critical, auto-specific issues such as avoiding key fob and car radio interference. The entry-level device, the MWCT1001A, provides a comprehensive and cost-effective multi-coil wireless charging transmit solution, while the MWCT1003A is the premium option providing more feature-rich capabilities. Integrating technologies such as Near Field Communication (NFC), multi-standard support, or CAN technology is easy using MWCT1003A, and is showcased on the reference design – WCT-5WTXAUTO. The auto-focused ICs meet AEC-Q100 requirements and support any 5W coil topology.
For consumer applications, Freescale is offering the MWCT1000 Qi-certified transmit controller IC and the associated WCT-5W1COILTX reference design, addressing 5W single-coil applications. This turnkey solution dramatically reduces time-to-market, provides exceptional performance and low bill-of-materials cost, while maintaining the principle of design flexibility. For even greater design freedom and feature integration, Freescale offers the MWCT1101 controller IC.
