BQ27Z846EVM
Overview
The BQ27Z846 evaluation module (EVM) is a system-level board created to enable users to evaluate the functionalities of the BQ27Z846 fuel gauge within a system. The BQ27Z846 EVM is suitable for applications in which the battery pack is 1-S cell, meaning one series cell. The EVM includes a BQ27Z846 battery fuel gauge, a high-side and low-side current sense resistor, integrated high-side protections, an ENAB wake button, a charger wake button, and other header options to allow for some modifications to meet the intended application.
Features
- Complete evaluation system for the BQ27Z846 LiIon Battery Pack Manager Evaluation Module.
- Populated circuit module for quick setup
- Software that allows data logging for system analysis
- Integrated high-side and low-side current sense resistor
- Integrated high-side protections
- Dynamic Z-Track™ algorithm

Release Information
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.
Requirements:
- Hardware: MKST-3P-ALT-EV2300
- Supported operating systems: Windows (32 and 64 bits)
- Software: Microsoft Visual Studio 2010 C++ Runtime redistributable
Features:
- Collection of command line executables for Windows
- Small executable size with few dependencies
- Fast programming
- Supports BQFS/DFFS and SREC file formats
- Provides C API for custom code development
- Callable from other programs for automation
- Portable design simplifies deployment
- Separately downloadable support software to enable legacy software like BQEVSW and ADVANCED-BQMTESTER to work with MKST-3P-ALT-EV2300
Getting started:
1. Download the software
2. Run the installer
3. The executables, C API and Python API files can be found in the install location
4. Run the command line executable without arguments to get usage help. Refer to Readme.txt in the install folder for more information and how to get help using the command line.
What's new
- Added support for BQ78350 and BQ34Z100
