Maxim Announces Power Management Chip for IoT and Wearables
Published2016.01.07 11:37
Maxim Integrated announced the 'MAX14720', a power management chip (PMIC) that optimizes power and battery life in the fields of medical and fitness wearables and the Internet of Things (IoT).Improving battery life and achieving low power consumption are key considerations in the development of wearable and IoT products. The MAX14720 is a power management chip optimized for non-rechargeable batteries, such as coin and alkaline batteries, where size and energy efficiency are critical.
The electronic battery seal extends battery life by effectively disconnecting the battery connection before initial power supply. The MAX14720 reduces the number of components and enables a much smaller form factor design by integrating the functionality of five devices: a power switch, a linear regulator, a buck regulator, a buck-boost regulator, and monitoring.
While most battery power management chips operate at 3 volts (V), the MAX14720 operates at a low voltage of 1.8V and works with primary batteries. Maxim's proprietary low standby current technology significantly extends the runtime of wearable systems. The electronic battery seal extends storage life and enables a fully sealed housing. The MAX14720 reduces component costs and space with high-value features such as push-button input monitoring, power-up sequencing, and voltage rail monitoring.
"Maxim Senior Business Manager Frank Dowling said, 'Maxim has established a strong position in the rechargeable wearable market and is effectively leveraging the expertise and proprietary technology gained in rechargeable wearables in the non-rechargeable wearable market as well.'"
Angela McIntyre, Research Director, and Michael Reitz, Senior Research Analyst at market research firm Gartner, stated, “The wearable fitness and health market is projected to reach $14.4 billion in 2020 with the sale of approximately 190 million devices,” adding, “System design for wearables will become more simplified by utilizing display drivers, optoelectronics, USB charging interfaces, small NOR memory, and power management chips, along with basic microcontroller (MCU)-based processing, Bluetooth and Wi-Fi communication, accelerometers, and gyroscopes.”
The MAX14720 is available in a 25-bump, 0.4mm pitch, 2.26mm x 2.14mm wafer-level package (WLP) and operates in a range of -40°C to +85°C.

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.
