Transmitter controller IC for wireless charging of unmanned vehicles and robotics introduced by Infineon

June 15, 2023
WLC1150 transmitter is for efficient flexible thermal management, low electromagnetic interference, and integrated adaptive foreign object detection.

MUNICH – Infineon Technologies AG in Munich is introducing the WLC1150 wireless charging transmitter controller integrated circuit to provide a streamlined and user-friendly experience for portable products across a wide range of industries.

The device is for applications that need high wireless power transfer, such as industrial applications, health care equipment, robotics, unmanned vehicles, docking stations, and smart phone chargers.

The WLC1150 transmitter is designed for high efficiency, flexible thermal management options, low electromagnetic interference (EMI), integrated adaptive foreign object detection (FOD), inverter control, and several other features. The WLC1150 uses several methods to tune the adaptive FOD, including Q-factor, resonant frequency and power.

The transmitter supports 50-Watt wireless power transfer using a high-power proprietary charging protocol and an input voltage range of 4.5 to 24 volts. The integrated fan buck controller cools the interface surface during high-power delivery. It also includes integrated gate drivers for the inverter, which is controlled by frequency, duty cycle, and variable voltage.

It also integrates a USB type-C power delivery (PD) controller that supports the latest version of USB-PD 3.1 with programmable power supply (PPS) mode. The WLC1150 complies with the WPC Qi 1.3 with EPP, basic power profile (BPP), and proprietary power delivery extension (PPDE).

It supports systems with input power supplied from either USB PD/PPS or fixed input from a DC power supply. With either input configuration, the transmitter does not require a front-end DC-DC converter. This helps to significantly improve system efficiency.
