Freescale Semiconductor has introduced a range of fully programmable wireless charging ICs and reference designs targeting automotive and consumer applications. The new Wireless Power Consortium (WPC) Qi-certified transmit controller ICs and reference designs are fully qualified and available now.
Unlike competing products that prohibitively restrict customisation, Freescale’s new offerings enable the rapid development of differentiated wireless charging systems. Flexibility is provided through a programming interface that places control of the end-solution in the product developer’s hands.
The 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 – MWCT1001A – provides a comprehensive and cost-effective multi-coil wireless charging transmit solution, while 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 WCT-5WTXAUTO reference design. The auto-focused ICs meet AEC-Q100 requirements and support any 5 W coil topology.
For consumer applications, Freescale offers the MWCT1000 Qi-certified transmit controller IC and the associated WCT-5W1COILTX reference design, addressing 5 W single-coil applications. For greater design freedom and feature integration, the MWCT1101 is also available.
