Contactless power and sensing ICs
Single-chip solutions for NFC-based configuration, actuation and sensing applications
Near-field communication (NFC) is a mature technology for contactless exchange of data over short distances. Besides the data exchange, the NFC technology itself can also transfer power from the polling device to the receiver devices. Due to the working principle of resonant coupling, power transmission via NFC is efficient and user-friendly because it is less sensitive to antenna alignment. The combination of data exchange and energy transfer in one interface and the availability in billions of smartphones makes NFC an exciting enabler for the following use cases:
Programming or configuring product operation parameters is sometimes complicated because of access problems or equipment requirements. Using an NFC interface, contactless or even passive operation can be performed anywhere. Modern LED power supplies are already equipped with the NFC interface to enable operation parameter configuration in production, sales channel, and the field. Infineon’s NLM product series is designed for that purpose and provides value-add features like the Constant Lumen Output (CLO) function.
In the IoT age, smart devices help people make their life easier and the end product more sustainable. The NFC technology provides an option to develop battery-less smart devices that operate when the NFC reader device, like a mobile phone, is present. As a complement to mainstream active IoT technology, passive NFC technology is suitable for use cases like a passive smart lock or passive sensor inlay.
Infineon’s NFC tag-side controller family supports customers to develop cost-effective, miniaturized, actuation or sensing applications operating in either passive or active mode.
