Nuvoton Technology Japan has announced the upcoming mass production of two new 16‑cell battery‑monitoring ICs, the KA49703A and KA49713A, slated for September 2026. Designed specifically for AI server battery backup units (BBUs), these chips address the growing need for uninterrupted power in data centers that now serve as critical infrastructure.
Key to reliability is the built‑in daisy‑chain communication, which lets up to 16 cells be monitored on a single bus, cutting wiring complexity and cost. This topology simplifies integration into dense server racks while delivering voltage and temperature data, allowing the backup system to quickly respond to fluctuations and keep AI workloads running.
The launch cements Nuvoton’s role in AI power‑management, delivering a solution that meets data centers’ strict uptime needs. OEMs can integrate the new BMICs into next‑generation AI servers by September 2026, confident the technology will boost reliability, scalability, and total cost of ownership.
