Evaluation and Demonstration Boards and Kits are a set of tools for electronic hardware designers, allowing users to explore, prototype, and test their products. One example is the BQ4050EVM-561 Evaluation Module kit — a high-performance and low-footprint board for evaluating battery fuel gauges. This kit provides users with a convenient platform for gauging the performance of the BQ4050, the industry’s leading fuel gauge.

The BQ4050EVM-561 includes an LED indicator for battery capacity, a DC/DC converter, and integrated support for I2C communications. This allows designers to quickly and accurately measure the performance of the BQ4050 in their design. It also includes an optional LCD display, which can be used to monitor the performance of the gauge in real time.

The device runs on a single-cell Li-Ion battery and is designed to be electrically and thermally compatible with a wide variety of battery cells. The board can be used to quickly evaluate the fuel gauge’s performance, such as voltage regulation, current monitoring, temperature and current calibration, charge/discharge slope, and balanced charge algorithms.

The BQ4050EVM-561 utilizes the integrated power measurement and protection IC, which helps users accurately measure the energy consumed by the fuel gauge and protect it from over voltage, under voltage, and over temperature events. The integrated protection thresholds can be changed depending on the battery technology used, which helps maintain accuracy and reduce complexity.

The BQ4050EVM-561 offers extensive logging and debugging capabilities. It can record key performance indicators, such as voltage, current, temperature, and charge and discharge rate, on a 16-bit Analog to Digital Converter. This data can be viewed on the optional LCD display, providing a quick look into the performance of the fuel gauge. It can also record events, such as alarms, alerts, and low-voltage or temperature warnings, enabling users to quickly diagnose issues.

The BQ4050EVM-561 kit provides users with a convenient platform for evaluating the performance of BQ4050 fuel gauges. It is designed to be electrically and thermally compatible with a wide variety of battery cells and includes integrated power measurement and protection ICs for accurate measurements and superior protection. It also features an LED indicator for battery capacity, a DC/DC converter, and integrated support for I2C communications, as well as extensive logging and debugging capabilities for quick troubleshooting and performance evaluation.
