First wireless power transmitter to support Apple 7.5W and Android fast-charge modes
At the heart of the reference design is the 15W P9242-G transmitter IC which provides for extremely accurate fixed frequency operation for EMI compatibility with EN303 417 and enhanced smartphone application co-existence. The kit supports the WPC Qi Baseline Power Profile (BPP) and Extended Power Profile (EPP) up to 15W with enhanced Foreign Object Detection (FOD) for a highly reliable and robust user experience. Additionally, the converged transmitter design supports all major fast wireless charging protocols and USB-C power delivery (PD) .
“Apple’s announcement in September to include Qi-based wireless charging in the latest iPhone models has dramatically increased user interest and with the recent release of the Apple iOS 11.2 upgrade, owners of these smartphones can now enjoy the benefits of fast wireless charging,” said Chris Stephens, general manager of IDT’s Mobile Power and Sensing Division. “This converged solution allows both Android and iOS smartphone fast wireless charging.”The P9242-G-EVK reference kit has an input voltage range of 11V to 19V, supports USB or USB Type-C connectors and can be upgraded in the field through the system flash memory. The reference kit has a quiescent power of less than 900mW.
IDT is sampling the product now and will release for broader availability in January, 2018. Visit idt.com/wireless power for more information including technical documentation.
