BQ27Z746-DEVICE-FW
BQ27Z746 系列监测计固件
BQ27Z746-DEVICE-FW
概述
BQ27Z746-DEVICE-FW 是仅固件 (FW) 版本，可刷写到 BQ27Z746 产品等任何现有硬件中。该固件采用已获专利的 Impedance Track™ 技术创建基于电池组的解决方案，为 1 节锂离子电池和锂聚合物电池组提供电量监测、保护、差分电池检测模拟输出和身份验证等一系列丰富的功能。
BQ27Z746 系列监测计固件利用其集成的高性能模拟外设，可测量并准确记录锂离子或锂聚合物电池的可用容量、电压、电流、温度和其他关键参数，并将这些信息报告给系统主机控制器。集成式保护可针对过压 (OVP)、欠压 (UVP)、充电/放电过流 (OCC/OCD)、短路放电 (SCD) 和电池检测保护（BCP、BCN、BDP 和 BDN）提供安全保护。
SHA-2 认证对认证码密钥使用安全存储器，确保识别真正的电池组。

Overview
The BQ27Z746-DEVICE-FW is a firmware (FW)-only release that can be flashed onto any existing hardware such as BQ27Z746 product. The firmware incorporates the patented Impedance Track™ technology to create a pack-based solution that provides a rich array of features for gas gauging, protection, differential battery sensing analog output, and authentication for 1-series cell li-ion and li-polymer battery packs.
Using its integrated high-performance analog peripherals, the BQ27Z746-DEVICE-FW firmware enables the device and measures and maintains an accurate record of available capacity, voltage, current, temperature, and other critical parameters in li-ion or li-polymer batteries, and reports this information to the system host controller. The integrated protection provide safety protection against Over Voltage (OVP), Under Voltage (UVP), Over Current in Charge/Discharge (OCC/OCD), Short Circuit Discharge (SCD), and Battery Sensing Protections (BCP, BCN, BDP and BDN).
SHA-2 authentication, with secure memory for authentication keys, enables identification of genuine battery packs.
BQ27Z746-DEVICE-FW is usable on any previous version of the BQ27Z746 hardware.

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.
新增功能
- Added support for BQ78350 and BQ34Z100
