release of the new Qi2 standard to redefine inductive wireless power transfer. Reflecting the enthusiastic industry response, Infineon Technologies is addressing the demand by introducing its first Qi2 Magnetic Power Profile (MPP) charging transmitter solution and reference design kit REF_WLC_TX15W_M1.
The new MPP in Qi2 offers magnet-based fixed positioning, which contributes significantly to improve the user experience, turning the "snapping" between devices an intuitive and reliable routine. This new standard guarantees significant benefits in automotive and consumer applications, such as in-cabin wireless charging, smartphones and TWS earbud cases, portable speakers, and healthcare equipment through better efficiency and safety.
The new Infineon reference design kit is highly integrated and form factor optimized with a diameter of less than 43mm, with a programmable wireless charging transmitter centered around an Infineon WLC1 controller. It demonstrates the capabilities of Infineon's Qi2-capable WLC1 which is already available on the market. The IC integrates a microcontroller (MCU) with Flash memory, a 4.5V to 24V DC input buck-boost controller, inverter gate drivers, and factory-trimmed current sensing. It features analog protection peripherals, USB Power Delivery, and LIN as well as serial interfaces enabling efficient and smart power delivery.
The REF_WLC_TX15W_M1 board is supported with code examples in ModusToolbox to help developers take advantage of the IC’s configuration capabilities. The 15W Qi2 MPP solution board is backward compatible with a basic power profile (BPP) that allows receivers without MPP support to wirelessly charge at 5W. In addition, a multipath ASK demodulator and adaptive foreign object detection (FOD) are provided, making the design a robust and secure wireless power solution.
"With the emerging Qi2 standards, our programmable solutions offer the flexibility that the industry needs to adapt swiftly and offer differentiated features for automotive and consumer applications," says Ganesh Subramaniam, Senior Vice President and General Manager of the Wired Connectivity Solutions Product Line at Infineon.
The WLC1 transmitter controllers - WLC1515 for automotive, and WLC1115 for consumer applications - can be ordered now. The REF_WLC_TX15W_M1 development solution board is available on request.
