Utilizing the Qi2 reference design helps minimize customer risk in certifying their final product, which is required to pass through the Qi certification process. As it integrates several of Microchip’s automotive-qualified parts, the dual-pad charger also meets automotive standards for reliability and safety. The automotive-grade hardware and software solution enables easier automotive integration with support for AUTomotive Open System Architecture (AUTOSAR®) and AUTOSAR Microcontroller Abstraction Layer Architecture (MCALs), functional safety and more. An integrated CryptoAuthentication™ IC provides security to meet the stringent authentication requirement of Qi standards.
“The dual-pad reference design provides manufacturers of automotive charger modules with the flexibility and programmability to optimize MPP Power Loss Accounting (MPLA) and Q-Based Foreign Object Detection (Q-FOD) and minimize time to certification. It also allows for the seamless integration into the automotive environment,” said
As part of the reference design, Microchip can deliver design files and software designed to create an easy design experience and first-pass success. The design includes the dsPIC33 DSC and a TA100/TA010 Trust Anchor secure storage subsystem provisioned by Microchip as a licensed
