Texas Instruments BQ20Z70EVM-001-EV2300


This EVM is a complete evaluation system for the bq20z70/bq29330/bq29410 Li-Ion smart battery chipset. The EVM includes one bq20z70/bq29330 and the independent 2nd level overvoltage protection bq29410, the circuit module with current sense resistor and thermistor, an EV2300 PC interface board for gas gauge interface, a PC serial cable (USB), and Windows-based PC software. The circuit monitors and predicts capacity, performs cell balancing, monitors critical parameters, protects the cells from overcharge, over discharge, short circuit, and overcurrent in 2-, 3- or 4-series cell Li-Ion or Li-Polymer battery packs. The circuit module connects directly across the cells in a battery. With the EV2300 interface board and software, the user can read the bq20z70 data registers, program the chipset for different pack configurations, log cycling data for further evaluation and evaluate the overall functionality of the bq20z70/bq29330 and bq29410 solution under different charge and discharge conditions. Please refer to the bq20z70EVM-001 User Guide and the datasheets of the bq20z70, bq29330 and bq29410 for full functional descriptions. The user guide has information on how to install the software, connect the evaluation setup, and use the main features of the evaluation kit.

Bundled with

The EV2300 is a USB-based interface board for a PC that can be used to evaluate battery fuel gauge circuits designed with Texas Instruments' ICs. The EV2300 has connections on it for a USB cable and also accepts inputs from a battery fuel gauge circuit's communication port (SMBus or HDQ). By running the appropriate PC software for the corresponging fuel gauge IC, the EV2300 interface board allows the user to evaluate the battery fuel gauge circuit.
