BQ27425EVM-G2A
概要
The BQ27425EVM-G2A evaluation module is a complete evaluation system for the bq27425-G2A. The EVM includes one bq27425-G2A circuit module with an integrated current-sense resistor. A separated orderable EV2400 PC interface board for gas gauge interface along with a PC USB cable, and Windows™-based PC software is needed when using this EVM. The circuit module includes one bq27425-G2A integrated circuit and all other onboard components necessary to monitor and predict capacity for a system-side fuel gauge solution. The circuit module connects directly across the battery pack. With the EV2400 interface board and software, the user can:
- Read the bq27425 data registers.
- Program the chipset for different configurations.
- Log cycling data for further evaluation.
- Evaluate the overall functionality of the bq27425 solution under different charge and discharge conditions.
The latest Windows™ – based PC software can be downloaded from the product folder on the Texas Instruments Web site.
特長
- Single series cell Li-Ion battery fuel gauge
- Resides on system board
- Supports embedded or removable batteries

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:
- Hardware: MKST-3P-ALT-EV2300
- Operating system: Windows (32 or 64 bit)
- Software: Microsoft Visual Studio 2010 C++ Runtime redistributable
Features:
- Enable use of MKST-3P-ALT-EV2300 in older software like BQEVSW and BQEASY
- Switch back to use of EV2300 in older software like BQEVSW and BQEASY
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.

Description:
BQMTESTER-MKST-UPDATE software is a software update for BQMTESTER(BQMTESTER Multi Channel Test and Program software) and ADVANCED-BQMTESTER(Advanced bqMTester Multi-Station Test and Program Software) 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 BQMTESTER and ADVANCED-BQMTESTER software from/to EV2300 to/from MKST-3P-ALT-EV2300. There are also some changes required on the hardware side as described in the PDF guide in the install folder.
The program requires administrator privileges.
Requirements:
- Hardware: MKST-3P-ALT-EV2300, 3.3V LDO with connectors, BQMTESTER or ADVANCED-BQMTESTER board
- Supported operating systems: Windows (32 or64 bits)
- Software: Microsoft Visual Studio 2010 C++ Runtime redistributable
Getting started:
1. Download the software
