The BQ25600EVM-771 is a high quality, industry-grade modular evaluation board that is specifically designed for power management applications in the field of telecommunications and electronics. It is a perfect choice for engineers and developers trying to build more efficient and reliable power supply structures for a wide range of products and services.

The BQ25600EVM-771 was designed in conjunction with Texas Instruments’ BQ25600 Buck-Boost battery charger. It features charging algorithms and schemes compliant with the Li-Ion Battery Charging Standards. With fast charge and adaptive input source current levels, this evaluation board can extend the operating time of many battery operated devices.

The BQ25600EVM-771 is an essential tool for exploring the features and capabilities of the BQ25600 buck-boost charger. The evaluation board includes an LED indicator that displays the battery charge status for easy monitoring and adjusting of the charging process. Additionally, it has an analog on/off control pin for programming the charging parameters.

At the core of the BQ25600EVM-771 evaluation board lies the BQ25600S which is a synchronous buck-boost battery charger with integrated voltage balancing for multi-cell Li-Ion batteries. The Buck-Boost switching regulator switches between buck and boost mode depending on the voltage on its input and output terminals. This technology enables a current/voltage step-down and step-up in both directions, allowing high efficiency near 90% over the entire operating range.

The BQ25600EVM-771 is based on the Buck-Boost switching regulator from Texas Instruments and is capable of supplying up to 5A of output current. Its input voltage range is from 2.5V to 16V and its output voltage range is from 0.6V to 18V. This evaluation board is designed to meet the needs of advanced power management applications and includes various features such as Vin-UVLO (Voltage Undervoltage Lockout), Power Good Flag, Soft Start, and integrated voltage balancing.

The BQ25600EVM-771 also includes charging algorithms compliant with the Li-Ion Battery Charging Standards, allowing fast charge and adaptive input source. The fast charge feature can be enabled by setting a switch inside the board. Additionally, the adaptive input source adjusts the average charge current to match the capability of input source power, reducing the need of a large external power source for charging.

The BQ25600EVM-771 evaluation board also includes adjustable overvoltage, overcurrent and overtemperature protection. This protection system ensures that batteries are safely charged and prevents damages by overcharging and short-circuiting. This protection system also features a low-battery protection and power good flag for monitoring the charge process.

The BQ25600EVM-771 evaluation board is an invaluable tool for developers, engineers, and researchers looking to explore the features and capabilities of the BQ25600 Buck-Boost charger. By providing an easy-to-use platform, this evaluation board allows for fast and accurate testing of different configurations, making it a flexible and powerful tool for research and development purposes.
