LC03-3.3 SOP8 TVS Static Protection 3.3V

On February 2, 2010, Texas Instruments (TI), headquartered in Dallas, Texas, unveiled what it claims to be the world's smallest battery management integrated circuit (IC). This breakthrough innovation, the bq3060, transforms standard batteries into intelligent ones capable of continuously and precisely measuring key parameters like available power, voltage, current, temperature, and more, specifically designed for Lithium-Ion (Li-Ion) battery applications.

Beyond just enhancing functionality and security, the bq3060 significantly cuts down on both cost and size. It comes in a compact 24-pin TSSOP package, measuring just 7.8 mm x 6.4 mm, which represents a 50% reduction in size compared to most advanced gas gauge solutions currently available. This smaller footprint allows manufacturers to design slimmer and lighter battery packs, ideal for various portable devices including commercial, medical, and testing equipment.

The bq3060 boasts several cutting-edge features that set it apart from competitors. Its advanced CEDV (Compensation Discharge End Voltage) monitoring technology ensures highly accurate fuel gauging. Additionally, its ultra-low power consumption mode, which uses less than 69 μA, helps extend battery life while reducing energy waste. For enhanced security, the device supports SHA-1 authentication, helping original equipment manufacturers (OEMs) verify host-to-battery compatibility. Moreover, it offers flexible communication options via a two-wire SMBus 1.1 interface with high-speed programming at up to 400 kHz, speeding up the development and testing process for battery packs.

In terms of availability, the bq3060 is already shipping in large volumes and can be purchased directly from TI or through its authorized distributors worldwide. Alongside the product launch, TI has made sample units and comprehensive application guides accessible to customers, ensuring seamless integration into new designs.

Overall, the bq3060 represents a significant leap forward in battery management technology. By offering superior performance in a smaller form factor, it opens up exciting possibilities for future innovations across multiple industries. Whether you're working on portable electronics, healthcare devices, or industrial tools, this tiny yet powerful IC could play a pivotal role in your next project.
