Battery Fuel Gauge IC integrates various protection features.
Press Release Summary:
Supplied in 24-pin, 7.8 x 6.4 mm TSSOP, bq3060 turns lithium-based battery into smart battery that measures and maintains accurate record of available capacity, voltage, current, temperature, and other critical parameters. Safety is also ensured via SHA-1 authentication as well as short-circuit and discharge protection. Consuming less than 69 µA, IC supports 2-wire SMBus 1.1 interface with 400 kHz programming option and also offers compensated end-of-discharge voltage gauging.

TI Introduces Single-Chip Battery Fuel Gauge with Protection
DALLAS - Texas Instruments Incorporated (TI) today introduced the industry's smallest, full-featured battery fuel gauge integrated circuit for portable consumer, commercial and industrial applications. The bq3060 turns a battery into a "smart battery" that measures and maintains an accurate record of available capacity, voltage, current, temperature and other critical parameters for lithium-based batteries. The single chip also provides robust battery safety, including authentication, short-circuit and discharge protection. See: www.ti.com/bq3060-pr.
In addition to maximizing functionality and safety, the bq3060 dramatically reduces cost and size for smart batteries. The device comes in a 24-pin, 7.8-mm x 6.4-mm TSSOP package, and is a 50 percent smaller solution when compared to a high-end fuel gauge. The small size allows the chip to reduce the form factor of battery packs in many portable designs, including portable commercial, medical and test equipment.
Key features of the bq3060:
Availability and pricing
The bq3060 is available in volume now from TI and its authorized distributors. Suggested resale pricing is $3.55 in 1,000-unit quantities. Samples and application notes are available.
