Wireless charging products for applications in consumer electronics, industrial and automotive
In Infineon's product portfolios, designers can find everything necessary for wireless charging solutions since we and our partners are dedicated to design both competitive quality components including MCUs, Drivers, MOSFETs, authentication ICs and etc. and complete solutions (Transmitters and Receivers) for applications in consumer electronics, industrial and automotive. Now, you can start exploring our wireless charging products from two options:
- Infineon solutions (≤50W)
If looking for highly integrated solutions that can help simplify the design and power range up to 50W, you are recommended to start from our Infineon solutions.
- Partners’ solutions (>50W)
If looking for discrete or customized solutions built by our components or solutions with the power range beyond 50W, you are recommended to start from our partners' solutions.
Particularly, to secure you, your data, and your devices, Infineon provides proper components and solutions to achieve Foreign object detection (FOD) and authentication for Qi standards.
Foreign object detection in inductive wireless charging
FOD is a safety mechanism in wireless power systems that automatically interrupts power delivery when interference from a foreign object is detected which can be coins, paper clips or other metal objects. The interference will significantly impact efficiency and pose a major safety hazard for devices and end users. Infineon’s premium semiconductor components including the low capacitance figure of merit (FOMCoss) of our OptiMOS™ product family and a high-accuracy ADC in the XMC™ or highly integrated Wireless Charging ICs enable highly efficient foreign object detection to determine power loss or quality factor deviation for safe and seamless wireless power operation.
Authentication for Qi wireless charging
The low-quality or non-standard chargers become a real issue in the global wireless charging market. They communicate in the standard protocol but have not passed certification in a WPC lab, which can lead to unintentional behavior of the transmitter and even damage receiving devices. At Infineon, the OPTIGA™ Trust family including the latest OPTIGA™ Trust Charge for WPC Qi 1.3 can help eliminate the potential damages by enforcing the standard and ensuring a uniform level of safety, security, and conformity.
