Contact BonChip Electronics today to learn more about how this innovative design can streamline your development process and ensure seamless Qi 2.0 integration.
Optimized Performance and Streamlined Development
The Qi2 reference design is powered by a single dsPIC33 Digital Signal Controller (DSC), providing efficient control and optimized performance for your wireless charging application. This design supports a key feature of the new Qi 2.0 standard: the Magnetic Power Profile (MPP) with magnetic alignment between the transmitter and receiver.
The flexible software architecture of the dsPIC33 allows for the combined support of both MPP and Extended Power Profile (EPP) of Qi 2.0 with a single controller. This simplifies development and reduces component count.
Reduced Risk and Faster Time-to-Market
Utilizing the Qi2 reference design minimizes your risk when certifying your final product for Qi compliance. The design integrates several automotive-qualified parts from Microchip, ensuring it meets stringent automotive reliability and safety standards.
Furthermore, the automotive-grade hardware and software solution allows for easier integration into automotive environments. It supports AUTomotive Open System Architecture (AUTOSAR) and AUTOSAR Microcontroller Abstraction Layer Architecture (MCALs), functional safety features, and more. An integrated CryptoAuthentication™ IC provides robust security to meet the strict authentication requirements of Qi standards.
Benefits for Automotive Charger Manufacturers
“The dual-pad reference design offers significant advantages for manufacturers of automotive charger modules,” said Joe Thomsen, vice president of Microchip’s digital signal controllers business unit. “It provides flexibility and programmability to optimize MPLA (Magnetic Power Loss Accounting) and Q-FOD (Q-Based Foreign Object Detection), while minimizing time to certification. Additionally, it allows for seamless integration into automotive environments.”
