The Texas Instruments BQ27427 battery fuel gauge is a single-cell gauge that requires minimal user-configuration and system microcontroller firmware development, leading to quick system bring-up.
Three chemistry profiles are preprogrammed to enable minimal user-configuration, and to help manage customer inventory across projects with different battery chemistries. The BQ27427 battery fuel gauge has very low sleep power consumption leading to longer battery run time. Configurable interrupts help save system power and free up the host from continuous polling. Accurate temperature sensing is supported with an external thermistor.
The BQ27427 battery fuel gauge uses the patented Impedance Track™ algorithm for fuel gauging, and provides information such as remaining battery capacity (mAh), state-of-charge (%), and battery voltage (mV).
Battery fuel gauging with the BQ27427 fuel gauge requires connections only to PACK+ (P+) and PACK– (P–) for a removable battery pack or embedded battery circuit. The tiny, 9-ball, 1.62 mm × 1.58 mm, 0.5 mm pitch NanoFree™ chip scale package (DSBGA) is ideal for space-constrained applications.

Battery Management Studio (bqStudio) offers a full suite of robust tools to assist with the process of evaluating, designing with, configuring, testing, or otherwise utilizing TI Battery management products. This includes features that provide full access to registers and data memory including support for real-time watching, graphing, and logging, an easy interface to send commands, direct low-level communication and I/O, as well as automated and guided support for configuration, calibration, performing a learning cycle, and generating useful files for taking the device to production.
Older products such as bq20xxx and bq30xxx are not supported in bqStudio. Download the specific evaluation software from the appropriate product page.
Requires: EV2400 or MKST-3P-ALT-EV2300
Software installer to enable BQEVSW to use MKST-3P-ALT-EV2300
Software manifest
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.
