ST Boosts Wireless Charging Speed, Efficiency, and Flexibility with 70W High-Power Chipsets

29.11. 2021 | News

STMicroelectronics’ STWLC98 integrated wireless power receiver delivers faster wireless charging and flexible charge sharing for diverse portable and mobile devices for home, office, industry, healthcare, and in-car applications. When combined with the STWBC2-HP transmitter IC, the complete transmitter-receiver system can deliver up to 70W on the receiver end at high system efficiency.

The STWLC98 can fully charge today’s high-end smartphones, which contain high-capacity batteries, in just under 30 minutes. In addition, the new device extends opportunities for ultra-fast and convenient charging, free of cables, sockets, and restrictive connections, to a host of new applications and contexts. Moreover, contactless charging lets product creators simplify enclosure designs, reducing cost and complexity while encouraging new slimline styles and eliminating problems associated with the socket such as contamination.

Compliant with the Qi EPP 1.3 wireless-charging standard commonly used in the smartphone industry, the STWLC98 is managed by a 32-bit Arm® Cortex®-M3 core that supports a range of rich features including built-in protection; it comes with an embedded OS that simplifies Qi 1.3 standalone certification. On the transmitter side, the STWBC2-HP can work with ST’s STSAFE-A110 secure element to store official Qi Certificates and provides authentication that leverages state-of-the-art cryptography. Support for the Company’s innovative ST Super Charge (STSC) protocol enables fast charging up to the maximum power-transfer rate of 70W (more info).
