The Texas Instruments BQ27Z758 Impedance Track™ gas gauge solution is a highly integrated, accurate 1-series cell gas gauge and protection solution.
The BQ27Z758 device provides a fully integrated, pack-based solution with a flash programmable custom reduced instruction-set CPU (RISC), safety protection, differential battery sensing analog output, and authentication for 1-series cell Li-ion and Li-polymer battery packs.
The BQ27Z758 gas gauge communicates through an I2C compatible interface and combines an ultra-low power TI BQBMP processor, high accuracy analog measurement capabilities, integrated flash memory, N-CH high-side FET drive, and a SHA-2 Authentication transform responder into a complete, high-performance battery management solution.

Description:
BQ-BATTERY-PROGRAMMER-SW software development kit (SDK) is a collection of robust software command line tools that assist with the process of programming, testing, or assembling packs that use TI Battery management products. The executables in this software work with the MKST-3P-ALT-EV2300 MKS Technology alternative for EV2300 communications transceiver. The executables work with a single station but can be extended to multiple stations by using additional software and GUI from MKS Technology Inc. . Support for multiple stations is not included in this software.
There are multiple executables in the download, usually one per family of products. Older products such as BQ20xxx and BQ30xxx are also supported. Examples using the C++ programming language API and Python® programming language are provided for custom development.
