STMicroelectronics Unveils World’s Fastest
50W Qi Wireless-Charging IC
Safe, wireless delivery of high power to charge personal electronics must address a range of challenges including efficiency, reliable communication, Foreign Object Detection (FOD), and thermal, over-voltage, and over-current protection. A long-standing member of the
“ST’s latest STWLC88 wireless-charging IC provides the best solution for wireless-charging applications with industry-leading efficiency, highest power delivery, and maximum safety,” said
The STWLC88 incorporates multiple circuits to substantially reduce the external BoM (Bill of Materials), making it ideal for integration in a wide range of applications with restrictive PCB area requirements. Being WPC Qi 1.2.4 EPP compliant, the STWLC88 is fully compatible with all Qi EPP certified transmitters in the market. As a result, the STWLC88 offers state-of-the-art features that are critical for performance and safety and is ideal for medium- to high-power wireless-charging applications.
The STWLC88 is in production and available in a 4.0mm x 4.5mm x 0.6mm WLCPS 110-bumps 0.4mm pitch package, priced from
The STEVAL-ISB88RX evaluation board, containing the STWLC88 and a sophisticated GUI, is also available to simplify prototyping and significantly cut time to market with the 50W charger IC.
Technical Notes to Editors:
With its fully integrated ultra-low impedance, high-voltage synchronous rectifier, and low drop-out linear regulator, the STWLC88 achieves high efficiency and low power dissipation, critical for applications that are highly sensitive to unnecessary heat buildup. The power-charger chip features dedicated hardware and advanced algorithms that were developed to address challenges in ASK and FSK communication during high power delivery. Moreover, the STWLC88 comes with highly accurate Foreign Object Detection (FOD) and an integrated accurate current-sensing system to ensure high power delivery is performed safely and in a controlled manner.
The STWLC88 can also operate in high-efficiency transmitter mode to allow high-power charge-sharing mode. This is coupled with the STWLC88’s industry-first Q factor detection in a receiver device to ensure safe operation and protection to end-users.
An I2C interface allows firmware and platform developers to customize parameters in the device and the configuration can be programmed into the embedded FTP, which allows for more than 1000 times of re-programming. Additional firmware patching improves the IC’s application flexibility.
