Nuvoton Technology Corporation Japan has introduced it would start mass manufacturing of its KA49703A and KA49713A battery-monitoring built-in circuits (BMICs) in September 2026. The new ICs are designed for battery backup models (BBUs) utilized in AI servers, guaranteeing dependable and environment friendly energy techniques for steady operation.
Leveraging automotive-grade daisy-chain communication expertise, these BMICs help high-voltage BBU functions starting from 400V to 800V. The technique permits for techniques connecting as much as 55 gadgets in sequence whereas minimizing wiring wants and sustaining sturdy communication in high-voltage environments. This design reduces the requirement for extra microcontroller models (MCUs) and isolation elements, aiding system design simplification and enhancing reliability.
The compact QFP-48 package deal, measuring 7 mm by 7 mm, helps in addressing house constraints in AI server BBUs. Additionally, the ICs supply voltage measurement accuracy of plus or minus 2.9 millivolts, enhancing monitoring efficiency and security in next-generation energy techniques.
The KA49713A BMIC features a specialised transportation and storage mode that reduces shutdown present to lower than 0.1 microampere. This function minimizes battery depletion throughout transportation and storage of AI-server BBUs and large-scale power storage system installations, which frequently comprise quite a few lithium-ion cells. The diminished energy consumption considerably extends storage durations, lowers recharge wants, and contributes to decreased working prices.
With samples already accessible, Nuvoton Technology Corporation Japan goals to additional advance its battery-monitoring expertise to help a sustainable and extremely dependable power future. The firm’s efforts underscore its dedication to enhancing energy system architectures for AI server functions.
