Qi 1.3 Wireless Charging Reference Design
Microchip Technology has announced a new Qi 1.3 wireless charging reference design providing developers of wireless charging systems for automotive and consumer applications with the tools and support for the integration and certification of new-generation product designs.
The Wireless Power Consortium (WPC) recently released the Qi 1.3 specification that requires authentication for improved safety when transmitting up to 15W of power between a transmitter and a receiver, and for developers launching certified Qi 1.3 transmitters under tight timelines, this three-coil Qi 1.3 reference design has been designed to provide a head start for product development.
The reference design integrates secure storage subsystem software with the wireless power microcontroller (MCU) and is a flexible solution that enables custom topologies and foreign object detection (FOD) implementation.
