As the Qi2 standard reshapes the wireless charging landscape, CPS has introduced the WB8118, an all-in-one 15W transmitter chip. By packing an 8051 processor, full-bridge drivers, and advanced FOD detection into a tiny 3×4mm QFN package, it streamlines circuit board design and reduces interference. It is the ultimate tool for manufacturers looking to build high-performance Qi2 chargers without the headache of complex peripheral circuitry.
The WB8118 is built for performance. It features a high-speed 8051 core and a massive 288MHz PWM module, ensuring ultra-precise control over power delivery. Whether it's running off a 3.3V or 18V supply, the chip handles it effortlessly, supporting Qi2, Apple, and Samsung wireless standards. Safety is also baked in, with built-in protection for over-voltage, over-current, and temperature, plus a "deep-sleep" mode that keeps power draw negligible when not in use.
The WB8118 is already a proven winner. You can find it under the hood of Anker’s latest Qi2 3-in-1 chargers and magnetic power banks. By integrating control and drive functions, it helps brands cut down on extra parts, reduce EMI noise, and deliver a cool, stable 15W charging experience in devices that are thinner and sleeker than ever before.
