Infineon OPTIGA™ Trust Charge
The trusted authentication solution for wireless charging
An increasing number of products and applications support wireless charging – driven by its obvious ease and convenience. However, an inaccurate power supply can be harmful to the device and, worst case scenario, even to the user.
Infineon’s OPTIGA™ Trust Charge is a turnkey solution providing secured device authentication for inductive wireless charging according to the Qi 1.3 wireless charging standard. Secured authentication with OPTIGA™ Trust Charge contributes to device and user safety by protecting against fake chargers.
The turnkey setup – with full system integration support and all key and certificate material preprogrammed – minimizes customer effort for design, integration and deployment. OPTIGA™ Trust Charge comes with preprogrammed locked OS, locked application code, and host-side modules to integrate with host microcontroller software. Integration support includes a reference board and documentation for rapid design-in.
The Infineon OPTIGA™ Trust Charge authentication chip is certified to Common Criteria EAL6+ (high), thus exceeding the security requirements of the Qi 1.3 standard. Infineon is able to provide personalization and injection of the certificates and keys specified by the WPC in a secured and certified environment according to WPC requirements, making it easy for customers to build in security capabilities.
OPTIGA™ Trust Charge is part of Infineon’s OPTIGA™ Trust family, which offers a full range of embedded security solutions for the connected devices market. All OPTIGA™ products are based on secured hardware and software.
