Efficient and Easy-to-use wireless charging for smartphones, wearables, medical and industrial devices possible with the AURIX™ and XMC™ microcontroller families: Infineon Technologies AG offers flexible chip sets for high performance including software IP for smart and safe wireless charging applications.
Working with a systems solution partner, Infineon provides reference designs for both inductive and resonant wireless charging solutions for on-the-go charging, whether in the car, at home or in public places.
Automotive in-cabin wireless charging
The controller works seamlessly with power devices from Infineon to provide a complete charging solution:
- Voltage regulator and power MOSFET technology enable high efficiency power conversion, while network ICs serve for reliable communication according to highest automotive standards
- Supports the current 15W charging standards, including fast charge smartphones, and can support future changes through a software update
- An enhanced power stage architecture improves Electro Magnetic Interference (EMI) performance 10-15 dB over existing solutions on the market
- A newly-developed supplemental Foreign Object Detection system provides enhanced detection accuracy to meet critical customer safety requirements
“AURIX microcontrollers help the next-generation in-cabin wireless charging systems meet strict automotive safety, security, environmental and regulatory requirements”, said Ralf Koedel, Marketing Director Microcontroller at Infineon. “Still, they enable industry-leading charging performance and efficiency”.
Recharging consumer devices without complicated thermal management
The Infineon XMC microcontroller provides a powerful and cost-effective platform. The scalable architecture can support everything from a fast charge smartphone, to a 20 W robot, up to a 60 W drone and beyond.
Paired with power products, like MOSFETs and Driver ICs, this system can provide full power wireless charging without complicated thermal management, often achieving charging rates equivalent to wired charging.
The XMC based 2.5W low-power solution from Infineon is the industry’s lowest cost resonant wireless charger. It supports both one-to-one and multi-device charging on a single transmitter. By using a higher frequency, very small coils can be employed in a variety of form factors, with no regard to nearby metallic objects. These benefits make the technology ideal for charging wearables, headphones, smart clothing and other connected IoT applications.
