Infineon Technologies AG has launched the WLC1150 wireless charging transmitter IC for applications requiring higher wireless power transfer, such as healthcare equipment, power tools, and smartphones. The WLC1150 offers high efficiency, low EMI, integrated adaptive FOD, and flexible thermal management options.
Infineon Technologies AG has expanded its range of wireless charging (WLC) controller ICs with the launch of the WLC1150 wireless charging transmitter. This transmitter offers a cost-effective, highly integrated, and easy-to-design solution for applications requiring higher wireless power transfer, such as industrial applications, healthcare equipment, power tools, robotics, drones, and smartphone chargers supporting Qi Extended Power Profile (EPP).
The WLC1150 transmitter features integrated adaptive foreign object detection (FOD), inverter control, low electromagnetic interference (EMI), flexible thermal management options, and high efficiency. It uses multiple methods, such as resonant frequency, power, and Q-factor, to tune the adaptive FOD. The transmitter supports 50 W wireless power transfer and a wide input voltage range of 4.5 to 24 V. The device has a USB type-C power delivery controller. This controller supports the latest version of USB-PD 3.1 with programmable power supply mode (PPS).

In addition, the WLC1150 integrates gate drivers for the inverter, which is controlled by duty cycle, variable voltage, and frequency. It also features adjustable over-voltage protection (OVP), over-current protection (OCP), and over-temperature protection (OTP). The upcoming WLC1250 receiver IC can pair with the WLC1150 transmitter to provide end-to-end proprietary wireless power transfer solutions.
WLC1150 utilizes a 32-bit Arm Cortex-M0 processor, 128 KB Flash, 16 KB RAM, ADC, PWMs, and timers as peripherals. The versatile full-stack firmware offers extensive customizability for FOD, sensing, in-band communication, protection, and system parameters. Infineon’s ModusToolbox™ and WLC1150’s programmable features create unique and scalable wireless charging solutions for custom protocols and Qi spec. The WLC1150 transmitter is a streamlined and user-friendly solution that offers significant benefits for portable products across various industries.
