Infineon Technologies AG has introduced its first Qi2 Magnetic Power Profile (MPP) charging transmitter solution, which will be demoed at the company’s OktoberTech Silicon Valley tech collaboration, October 25. The new reference design kit, REF_WLC_TX15W_M1, will demonstrate the capabilities of Infineon’s WLC1 controller. The Qi2 wireless charging transmitter is available for both automotive and consumer applications.
Qi2 is the Wireless Power Consortium’s standard for inductive wireless power transfer. Infineon said the new MPP offers magnet-based fixed positioning with an intuitive user experience for significant benefits in automotive and consumer applications. These include in-cabin wireless charging, smartphones and EarPods cases, portable speakers and healthcare equipment.

The highly integrated reference design kit is form factor optimized with a diameter of less than 43 mm. It is a programmable wireless charging transmitter centered around Infineon’s WLC1 controller. The IC integrates a microcontroller (MCU) with Flash memory, a 4.5-V to 24-VDC input buck-boost controller, inverter gate drivers and factory-trimmed current sensing. It also includes analog protection peripherals, USB PD and LIN as well as serial interfaces for efficient and smart power delivery.
In addition, the 15-W Qi2 MPP solution board is backward compatible with a basic power profile (BPP) that allows receivers without MPP support to wirelessly charge at 5 W. Also provided is a multipath ASK demodulator and adaptive foreign object detection (FOD). Support for the REF_WLC_TX15W_M1 includes code examples in the ModusToolbox to help leverage the IC’s configuration capabilities.
The WLC1 transmitter controllers can be ordered now (the WLC1515 for the automotive package and the WLC1115 for the consumer package). The REF_WLC_TX15W_M1 solution board is available on demand. Visit www.infineon.com/qi2 for more information.
