New Wireless-charging Boards From STMicroelectronics for Industrial, Medical, and Smart-home Applications
STMicroelectronics has introduced a 50W, Qi-compatible transmitter and receiver combination to accelerate development of wireless charging for high-power applications such as medical and industrial equipment, home appliances, and computer peripherals.
意法半導體推出了一款50W、兼容Qi的發射器和接收器組合，以加快醫療和工業設備、家用電器和計算機外圍設備等高功率應用的無線充電開發。
Using ST's new wireless-charging solution, innovators can leverage the convenience and speed of wireless charging in applications that demand a higher power and shorter charging interval. These applications include vacuum cleaners, cordless power tools, drones and other mobile robots, medical drug delivery devices, portable ultrasound systems, stagelighting and mobile lighting, printers, and scanners. Free from cables, connectors, and complex docking arrangements, these products can become simpler, more affordable, and more robust.
使用意法半導體新的無線充電解決方案，創新者可以在需要更高功率和更短充電間隔的應用中利用無線充電的便利性和速度。這些應用包括吸塵器、無線電動工具、無人機和其他移動機器人、醫療藥物輸送設備、便攜式超聲波系統、舞臺照明和移動照明、打印機和掃描儀。這些產品無需電纜、連接器和複雜的對接安排，可以變得更簡單、更實惠、更堅固。
The STEVAL-WBC2TX50 transmitter board is capable of delivering up to 50W of output power using the ST Super Charge (STSC) protocol. STSC is ST's proprietary protocol for wireless charging at a faster rate than the standard protocols used with smartphones and similar devices, allowing quicker recharging of larger batteries. The board also supports the Qi 1.3 5W Baseline Power Profile (BPP) and 15W Extended Power Profile (EPP). The main component on-board is ST's STWBC2-HP transmitter system-in-package, which combines an STM32G071 Arm Cortex-M0 microcontroller and an application-specific front end. The front end provides signal conditioning and frequency control, a high-resolution PWM generator to drive the transmitter, and operates with any DC voltage from 4.1V to 24V. It also contains MOSFET gate drivers and a D+/D- interface for USB Power Delivery. In addition, the STWBC2-HP SiP can work with ST's STSAFE-A110 secure element to provide Qi authentication.
這個 STEVAL-WBC2TX50 發射器板能夠使用意法半導體超級充電 (STSC) 協議提供高達 50W 的輸出功率。STSC是意法半導體的專有協議，其無線充電速率比智能手機和類似設備使用的標準協議更快，可以更快地爲更大的電池充電。該主板還支持 Qi 1.3 5W 基準功率配置文件 (BPP) 和 15W 擴展功率配置文件 (EPP)。板載的主要組件是意法半導體 STWBC2-HP 發射器封裝系統，它結合了 STM32G071 Arm Cortex-M0 微控制器和特定應用的前端。前端提供信號調理和頻率控制、用於驅動發射機的高分辨率 PWM 發生器，並可在 4.1V 至 24V 的任何直流電壓下運行。它還包含 MOSFET 柵極驅動器和用於 USB 供電的 D+/D-接口。此外，STWBC2-HP SiP 可以與意法半導體配合使用 STSAFE-A110 提供 Qi 身份驗證的安全元素。
The STEVAL-WLC98RX receiver board is built to handle up to 50W charging power, to safely accommodate the full STSC capability as well as BPP and EPP charging. Features include support for Adaptive Rectifier Configuration (ARC), which extends charging distance by up to 50% to allow lower-cost coils and more flexible configurations. Accurate voltage and current measurement for Foreign Object Detection (FOD), thermal management, and system protection are also provided. This board uses ST's STWLC98 wireless power receiver IC, which contains a Cortex-M3 core and an integrated high efficiency synchronous-rectifier power stage with programmable output voltage up to 20V.
這個 STEVAL-WLC98RX 接收器板可處理高達 50W 的充電功率，可安全地容納完整的 STSC 功能以及 BPP 和 EPP 充電。功能包括支持自適應整流器配置 (ARC)，可將充電距離延長多達 50%，從而實現成本更低的線圈和更靈活的配置。還提供了用於異物檢測 (FOD)、熱管理和系統保護的精確電壓和電流測量。此主板使用 ST STWLC98 無線功率接收器 IC，包含 Cortex-M3 內核和集成的高效同步整流器功率級，可編程輸出電壓高達 20V。
Dedicated software tools, ST's STSW-WPSTUDIO for the STEVAL-WLC98RX and STSW-WBC2STUDIO for the STEVAL-WBC2TX50 are available to modify the configuration parameters, tailoring the operation of the device to the needs of customized applications. A comprehensive set of design documents is also available to assist development.
專用軟件工具，意法半導體 STSW-WPSTUDIO 適用於 STEVAL-WLC98RX 和適用於 STEVAL-WBC2TX50 的 STSW-WBC2STUDIO 可用於修改配置參數，根據定製應用程序的需求量身定製設備的操作。還提供了一套全面的設計文檔以協助開發。
The boards come with a Declaration of Conformity to the EU Radio Equipment Directive (RED) and are available from the ST eStore and from distributors. Pricing starts at $113.93 for the STEVAL-WLC98RX receiver and $109.03 for the STEVAL-WBC2TX50 transmitter.
這些主板附有符合歐盟無線電設備指令（RED）的聲明，可在ST eStore和分銷商處購買。起價爲113.93美元 STEVAL-WLC98RX 接收器和 109.03 美元的 STEVAL-WBC2TX50 發射機。
