ROHM Expands Market by Completing Wireless Charging Reference Design
Published2015.11.06 17:04WPC Qi certified for up to 15W wireless charging
ROHM Co., Ltd. (www.rohm.co.kr) announced that it has obtained the world's first Qi certification for Medium Power of the WPC Qi standard, an international standard for wireless charging, with a reference design equipped with a wireless charging control IC (BD57020MWV).
The WPC Qi Medium Power standard is attracting attention as a cutting-edge standard for wireless charging, enabling wireless charging for applications such as tablet PCs, and allowing smartphones to be charged up to three times faster than existing standards (5W or less).
In addition, as a countermeasure against foreign substance overheating to ensure the safety of wireless charging, a function to detect foreign substances before power charging has been installed.
ROHM has developed the industry's first wireless charging control IC (charging Tx side) compliant with the WPC Qi Medium Power standard, and has also developed a reference design based on this control IC.
The company stated that by obtaining Qi certification for the reference design, it is now possible to easily introduce wireless charging using the reference design, and it expects the range of applications to adopt it to expand further.
In addition, the reference design is on the ROHM website (http://rohmfs.rohm.com/en/products/databook/datasheet/ic/power/switching_regulator_system/bd57020mwv-eThe data sheet (.pdf) was released as an example of an application circuit.
Going forward, ROHM plans to obtain WPC Qi standard Medium Power Qi certification with a reference design equipped with a charging Rx-side wireless charging control IC (BD57015GWL) to promote the widespread adoption of wireless charging that creates a safe and comfortable environment.

The Problem with AI is Not Performance, but Trust
CEO Kang Min-seung emphasized at Snowflake's World Tour Seoul that generative AI has entered a phase where "trust" rather than accuracy becomes the key competitive advantage. As AI is applied to various tasks including consultation, risk management, and operational automation, incorrect data, erroneous responses, and bias are creating actual business risks. He pointed out that enterprises must build a trust layer above AI. To achieve this, accurate data management, semantic structuring, governance, and prompt security are essential. He explained that AI is not merely an automation tool but a technology that reorganizes the entire organization's workflows and decision-making systems. Snowflake provides a platform that supports this trust-based AI operation, emphasizing that enterprises should build "trustworthy AI" rather than "intelligent AI."

The Decisive Factor for AI Agents in Finance: "Trustworthy Data Infrastructure"
The key to spreading AI agents in the financial sector is establishing a trustworthy data system. KB Kookmin Bank is operating over 100 AI agents by 2025 and is promoting expansion to 300. AI is automating repetitive tasks across various areas such as consultation, risk management, wealth management, and relationship management. However, if data quality, governance, and semantic structuring are insufficient, errors and risks increase. KB is building an AI-Ready organization through a multi-model strategy of GPT, Gemini, and Claude, as well as a Snowflake-based data system. The bank emphasized that AI has entered a phase where it restructures not just simple automation but the entire work process and decision-making system.
