Freescale claims that in contrast to some competing products that restrict customisation, its new offerings allow design innovation and 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.
Freescale’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, 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 achieved using MWCT1003A, and is based on the reference design - WCT-5WTXAUTO. The auto-focused ICs meet AEC-Q100 requirements and support any 5W coil topology.
