The Texas Instruments BQ34Z100 is a fuel gauge solution that works independently of battery series-cell configurations, and supports a wide range of Li-ion and LiFePO4 battery chemistries. Batteries from 3 V to 65 V can be supported through an external voltage translation circuit that can be controlled automatically to reduce system power consumption.
The BQ34Z100 device provides several interface options, including an I2C slave, an HDQ slave, one or four direct LEDs, and an ALERT output pin. Additionally, the BQ34Z100 provides support for an external port expander for more than four LEDs.

General notes
Overview
bqProduction Hi-cell software offers a full suite of robust tools to assist with the process of configuring, calibrating, manufacturing and tracking printed circuit boards utilizing TI Battery management products. This includes features that allow writing a golden image followed by different types of calibration to provide desired levels of accuracy, writing date of manufacture, writing unique serial numbers, and finally validating limits for calibration parameters to spike out any inconsistencies in material. bqProduction Hi-cell software offers three (3) levels of access to allow strict control over the manufacturing process with the assembly line operator only having access to the "Start" button. bqProduction Hi-cell software supports a single station from a single computer and has inbuilt capability to maintain log files for the processed printed circuit boards.
Requires:
Mode of operation dependent: Requires 1mV, 1mA accurate external power supplies able to supply current required for calibration.
Features
MKST-3P-ALT-EV2300 is used as a substitute for EV2300. Separate installers may be provided for each family of products and build numbers may vary by device family.
Limitations: Recommended display resolution is 1920x1080 with maximum 125% scaling. The GUI may not show password fields and/or buttons may be moved out of the visible area when using other display settings.

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.
