For wireless charging system developers launching certified Qi 1.3 transmitters under tight timelines, Microchip’s three-coil Qi 1.3 reference design provides a head start for product development. The reference design fully integrates secure storage subsystem software with the wireless power microcontroller (MCU) and is a flexible solution, enabling custom topologies and foreign object detection (FOD) implementation.
As a regular member in the WPC, which sets global standards for wireless charging of mobile devices, Microchip provided expertise during development of the recently released Qi 1.3 specification. Qi 1.3 is a significant update from Qi 1.2.4 and mandates hardware-based authentication between transmitter and receiving devices for power transfer above 5W. By adhering to the new authentication standard, designers can ensure phones receiving 15W are receiving it from a Qi-certified authenticated transmitter to ensure safety.
“Wireless charging makes it easy and convenient for consumers to charge devices and, as a result, demand for these systems in the automotive and consumer segments is on the rise,” said
Included in Microchip’s reference design solution for wireless charging systems are all required elements: Qi controller, Qi application software, provisioned authentication controller that is a WPC-approved secure storage subsystem and crypto software libraries that execute on the Qi controller. The reference design includes complete schematics, bill of materials, software and design guidelines. Microchip is partnering with Avnet to make evaluation boards for the Qi reference design available to qualified customers around the world.
To support its Qi 1.3 wireless power solution, Microchip provides the dsPIC33C family of devices to run the Qi application software and the ECC608/TA100 secure storage subsystem provisioned by Microchip as a licensed
