The Texas Instruments BQ27Z558 Impedance Track™ gas gauge solution is a highly integrated, accurate 1-series cell gas gauge with a flash programmable custom reduced instruction-set CPU (RISC) and SHA-256 authentication for Li-ion and Li-polymer battery packs. The 1-series cell capability includes parallel cells for increased capacity.

The BQ27Z558 gas gauge communicates through I 2C-compatible and HDQ one-wire interfaces and includes several key features that can help facilitate accurate gas gauging applications. Integrated temperature sense functions (internal and external options) enable system and battery temperature measurements.
