Looking for STWBC2-HP Fixed Power Output Firmware

[孙尚香]

大家好，

我目前正在研究基于 STWBC50-HP 芯片的 2W 无线功率发射器。我的目标是在不使用 Qi 协议的情况下验证硬件功能，用于学习和测试目的。

我已经完成了发射器硬件设计，现在正在努力寻找一种无需 Qi 通信即可输出固定功率的固件，例如演示或示例项目，例如：

STWBC2-FW-固定功率输出、或任何允许恒定功率输出（例如，19V 2.6A）而无需协议协商的类似固件。

不幸的是，我在 ST 网站资源或 STM32Cube 软件包中找不到确切的固件。

任何人都可以分享下载链接或提供在哪里找到此固件的建议吗？
此外，如果有任何官方指南或步骤将 STWBC2-HP 配置为固定功率模式，那将非常有帮助。

提前致谢！

Hello everyone,

I'm currently working on a 50W wireless power transmitter based on the STWBC2-HP chip. My goal is to verify hardware functionality without using the Qi protocol, for learning and testing purposes.

I have completed the transmitter hardware design and am now trying to find a firmware that can output fixed power without needing Qi communication, such as a demo or example project like:

STWBC2-FW-FixedPowerOutputor any similar firmware that allows constant power output (e.g., 19V @ 2.6A) without protocol negotiation.

Unfortunately, I couldn’t find the exact firmware in the ST website resources or STM32Cube packages.

Can anyone share a download link or provide suggestions where to find this firmware?
Also, if there are any official guidelines or steps for configuring STWBC2-HP for fixed power mode, that would be very helpful.

Thanks in advance!

Hello,

The STWBC2-HP is compliant to the Qi standard as you know.

It is specified that the receiver "monitors" the power transfer, meaning that the level of power generated by the charger is controlled by the receiver. The charger will adapt it bridge voltage, frequency, duty cycle to the requested power. It can not decide by itself of a fixed output voltage and current.

The fixed power mode you are looking for is not possible.

Best regards.
