As various charger manufacturers, including automotive product manufacturers, strive to comply with the Qi® v2.0 (Qi2) wireless charging standard, Microchip Technology (Asia General Manager and Korea Representative Han Byung-don), a global leader in microcontrollers, mixed-signal, analog semiconductors, and flash-IP solutions, has launched a Qi 2.0 dual-pad wireless power transmitter reference design.

The Qi2 reference design is driven by a single dsPIC33 digital signal controller (DSC) and provides efficient control functions to achieve optimized performance.

One of the new features of the new Qi2 wireless charging standard recently announced by the Wireless Power Consortium (WPC) is the introduction of the Magnetic Power Profile (MPP), which supports magnetic alignment between the transmitter and the receiver.

Microchip DSC's flexible software architecture supports Qi 2.0 wireless charging by combining MPP and Extended Power Profile (EPP) with a single controller.

Microchip's Qi2 reference design minimizes the various difficulties customers may face during the Qi certification process in the final stage of product development where Qi standard certification is required.

This is because this dual-pad charger is a product composed of integrated automotive-certified components from Microchip that comply with automotive standards for reliability and stability.

In addition, these automotive-grade hardware and software solutions support the open software architectures AUTOSAR® (AUTomotive Open System Architecture) and AUTOSAR Microcontroller Abstraction Layer Architecture, making it easier to integrate automotive products and achieve functional stability.

In addition, the integrated CryptoAuthentication™ IC provides the security necessary to meet the stringent authentication requirements of the Qi wireless charging standard.

Joe Thomsen, Vice President of Microchip’s DSC business unit, stated, “The dual-pad reference design provides automotive charger module manufacturers with programming capabilities and design flexibility, such as optimizing MPP Power Loss Accounting (MPLA) and Q-Based Foreign Object Detection (Q-FOD) functions and minimizing the time required to obtain certification.”

He also stated, “This design enables seamless integration into the automotive environment,” adding that “automotive-grade design and extensive hardware and software support allow customers to optimize their final solutions and shorten the time to market.”

Microchip provides design files and software as part of the reference design, making the design environment more convenient and increasing the likelihood of success on the first try.

This design includes Microchip's dsPIC3It includes Microchip's TA100/TA010 Trust Anchor security storage subsystem, which holds DSC and WPC certification as a manufacturer certification body.

In addition, the ATA6563 CAN transceiver, MCP14700 gate driver, MCP16331 and MCP1755 regulator are also included.
