The Texas Instruments single-cell bq27320 battery fuel gauge requires very minimal configuration and system microcontroller firmware development, leading to quick system bring-up. The bq27320 uses the Compensated End-of-Discharge Voltage (CEDV) gas gauging algorithm for fuel gauging, and provides information such as remaining battery capacity (mAh), state-of-charge (%), runtime-to-empty (min), battery voltage (mV), temperature (°C) and state-of-health (%).
TI customers can tune chemistry parameters using TI’s web-based tool, GAUGEPARCAL.
Configurable interrupts help save system power and free up the host from continuous polling. Accurate temperature sensing is supported via an external thermistor.
Battery fuel gauging with the bq27320 requires only PACK+ (P+), PACK– (P–), and optional thermistor (T) connections to a removable battery pack or embedded battery circuit. The device uses a 15-ball NanoFree™ (DSBGA) package. It is ideal for space-constrained applications.

General notes
Overview
SingleCellbqProduction offers a full suite of robust tools to assist with the process of configuring, calibrating, manufacturing and tracking printed circuit boards utilizing TI Battery Battery management products. This includes features that allow writing a golden image followed by different types of calibration to provide desired levels of accuracy and finally validating limits for calibration parameters to spike out any inconsistencies in material. SingleCellbqProduction offers three(3) levels of access to allow strict control over the manufacturing process with the assembly line operator only having access to the "Start" button. SingleCellbqProduction supports 1 station from a single computer and has inbuilt capability to maintain log files for the processed printed circuits boards. The bqMTester hardware is incompatible with some single cell gauges.
Operating systems: Windows XP, Windows 7, Windows 10
Requires: MKST-3P-ALT-EV2300 (MKS-SAI-001), Precision voltage and current source/sink for calibration.
