BQ29312ARTHR

IC LITHIUM BATT PROTECTION 24QFN

Manufacturer: Texas Instruments

Categories: Battery Management

Quality Control: Learn More

Texas Instruments BQ29312ARTHR is a sophisticated lithium battery protection IC designed for managing 2 to 4 series cell lithium-ion/polymer battery packs. This component provides comprehensive fault protection against over-current, over/under-voltage, and short-circuit conditions. Its advanced functionality is accessed via an I2C interface, enabling precise control and monitoring of battery health. Packaged in a compact 24-VFQFN exposed pad (4x4mm), the BQ29312ARTHR is optimized for surface-mount applications requiring efficient thermal performance. The operating temperature range of -40°C to 85°C (TA) makes it suitable for demanding environments. This device is integral to applications in consumer electronics, electric vehicles, and power tools where reliable and safe battery operation is paramount. Available in Cut Tape (CT) packaging.

Integrated Circuit FAQs

An integrated circuit (IC) is a semiconductor chip that contains transistors, resistors, capacitors, and other electronic components on a single silicon substrate. ICs are the foundation of modern electronics and power devices such as smartphones, computers, automotive systems, and industrial equipment.

Integrated circuits work by routing electrical signals through microscopic semiconductor components fabricated onto a silicon chip. Depending on the design, ICs can process, amplify, store, or control electronic data.
