For 1W to 5W range, don't you think NFC Charging could be a better choice?NFC charging is more suitable for lower power range, typically up to 500mW. For applications in the range of 500mW to 100W, ST Wireless Power portfolio is a good fit.
What is the maximum distance between RX and TX coils?This depends on the coil design. Common designs are using 3mm to 5mm of gap. However, we have designed coils for 100W application with 2cm coil distance and with very good efficiency. In general, l...
Is it possible to send your own data from TX to RX and vice versa?It is possible to send data from Rx to Tx at a low data rate. As this communication is Qi native even for low power profiles, a MCU is requested to drive the transfer. In BPP (Baseline...
Is there any other competing standard for wireless charging and Qi?Airfuel Alliance representing resonance technology is the other competing technology, but Qi is dominating the market.
Are the ST wireless charging ICs Qi certified? What are the steps and costs involved in Qi certification?The Qi certification is for the end application and not the IC. The Qi certification mainly consists of compliance tests and interoperability tes...
Hi @Pavel A. ,Douglas was referring to the Webinar registration, but be aware that a lot of on demand content is available in our Academy and to register to those eLearning courses you just need your community account.
Hi @Community member ,I am checking with our authors, if they validate the proposal it will be put in the backlog of content to create and notify you when it will be available.Thank you,Laura
