BQ29703DSER Description

Short technical summary and product information.

The BQ29703DSER from Texas Instruments is an advanced single-cell battery protector IC specifically designed for Lithium-ion (Li-ion) and Lithium-polymer (Li-Po) battery applications. This device provides robust protection against common battery fault conditions, including overcurrent during charge and discharge, overvoltage, undervoltage, and load short-circuit conditions.

 

Key electrical specifications include an operating temperature range of -40°C to 85°C, a typical operating current of 4µA, and a shutdown current of 100nA. The input voltage range is from VSS – 0.3V to 12V. It supports overvoltage protection thresholds at 3.85V, 4.275V, 4.28V, 4.35V, and 4.425V, with battery overvoltage protection ranging from a minimum of 3.85V to a maximum of 4.6V.

 

Packaged in a compact 6-WSON (1.5x1.5 mm) or 6-WFDFN footprint, the BQ29703DSER is suitable for surface mounting. Its design facilitates integration into space-constrained battery packs, ensuring safety and reliability for single-cell battery systems.
