The Texas Instruments bq27741-G1 Li-Ion battery fuel gauge is a microcontroller peripheral that provides fuel gauging for single-cell Li-Ion battery packs. The device requires little system microcontroller firmware development for accurate battery fuel gauging. The fuel gauge resides within the battery pack or on the system’s main board with an embedded battery (non-removable). The fuel gauge provides hardware-based over- and undervoltage, overcurrent in charge or discharge, and short-circuit protections.
The fuel gauge uses the patented Impedance Track™ algorithm for fuel gauging, and provides information such as remaining battery capacity (mAh), state-of-charge (%), run-time to empty (minimum), battery voltage (mV), and temperature (°C), as well as recording vital parameters throughout the lifetime of the battery.
The device comes in a 15-ball BGA package (2.776 mm × 1.96 mm) that is ideal for space-constrained applications.

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:
Features:
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.

Description:
BQEVSW-MKST-UPDATE software is a software update for BQEVSW (bq Evaluation Software) and BQEASY (bq EV-Easy) to allow it to work with the MKST-3P-ALT-EV2300 MKS Technology alternative for EV2300 communications transceiver. This update installs a program that allows switching the USB transceiver target in software like BQEVSW and BQEASY from/to EV2300 to/from MKST-3P-ALT-EV2300.
The program requires administrator privileges.
Requirements:
Features:
Getting started:
1. Download the software
2. Run the installer and check the option to create shortcuts
3. Run the program using shortcut named BQEVSW-MKST-UPDATE from Start menu/Desktop
4. Allow administrator privilege when/if prompted
5. On the GUI window that opens, select the target transceiver to support and follow steps to switch
6. Connect matching transceiver and start BQEVSW, BQEASY or other similar software.
Note: BQMTESTER-MKST-UPDATE and BQEVSW-MKST-UPDATE both update the same software components. Switching the USB transceiver using any of these shortcuts will also switch it in the other.
