Southchip’s New SC58540 BMS Chip Ensures Compliance with New Safety Standards

As the new mandatory national safety standard for power banks looms, the industry is under pressure to improve battery monitoring and traceability. Southchip is stepping up with the SC58540, an all-in-one BMS chip for 2–4 series battery packs. Designed for high-power applications, it consolidates everything from high-precision monitoring and cell balancing to "black box" logging and encryption into a single 4mm×4mm chip. It’s the ultimate shortcut for manufacturers looking to meet strict 2027 safety regulations while simplifying their PCB designs.

The SC58540 is a technical powerhouse. It keeps tabs on every single cell with five independent NTC channels and Southchip's proprietary fuel gauge algorithm, keeping power display errors under ±2%—even in extreme cold or during intense fast charging. Safety is paramount: it uses a two-stage protection system that can trigger a physical 3-Terminal Fuse if a critical failure occurs, ensuring an absolute fail-safe. It also includes an RTC for event logging (a "black box" for your battery), hardware-level encryption (SHA256/ECC) to stop fakes, and dynamic cell balancing.

The SC58540 has already proven its worth in Southchip’s latest new-standard-compliant Bluetooth power bank demos. By handling data acquisition, safety protection, and anti-counterfeiting in one package, it makes it easier than ever for manufacturers to achieve full traceability and compliance. Whether you're building power banks, drones, or high-end tools, this chip is the new standard for battery management.
