LC03-3.3 SOP8 TVS Static Protection 3.3V

On February 2, 2010, Texas Instruments Incorporated (TI), headquartered in Dallas, Texas, announced the launch of the industry’s most compact battery management integrated circuit (IC) designed for portable consumer, commercial, and industrial devices. Known as the bq3060, this advanced IC transforms a standard battery into a "smart battery" capable of continuously and precisely measuring critical parameters like remaining power, voltage, current, temperature, and more, specifically tailored for lithium-ion (Li-Ion) battery systems.

Beyond enhancing functionality and security, the bq3060 significantly cuts down on both the cost and physical footprint of smart batteries. This innovative device comes in a compact 24-pin TSSOP package, measuring just 7.8 mm x 6.4 mm. Compared to conventional high-end gas gauge solutions, it boasts a remarkable 50% reduction in size. This compact design allows manufacturers to create slimmer and lighter battery packs for a variety of portable products, including commercial tools, medical devices, and testing equipment.

The key features of the bq3060 include:

• Advanced CEDV (Compensated End-of-Discharge Voltage) monitoring technology ensures precise gas gauge readings;
• An ultra-low-power mode consumes less than 69 μA, which maximizes battery runtime while conserving energy;
• SHA-1 authentication supports original equipment manufacturers (OEMs) in ensuring secure host-to-battery compatibility;
• A two-wire SMBus 1.1 interface with a high-speed 400 kHz programming option accelerates the design and testing of battery packs.

Availability-wise, the bq3060 is currently available in bulk quantities and can be purchased directly from TI or its authorized distributors. Additionally, evaluation samples and comprehensive application notes are readily accessible to aid developers in integrating the IC into their projects.

This breakthrough in battery management technology represents another step forward in TI's commitment to delivering cutting-edge solutions for the rapidly evolving world of portable electronics. As the demand for smaller, smarter, and more efficient energy storage systems continues to grow, the bq3060 stands out as a game-changing innovation that will undoubtedly shape the future of portable device design.
