IntroductionEvaluation and Demonstration Boards and Kits offer test environments and platforms for design engineers to quickly develop and verify circuit designs. The BQ25504EVM-674 is a complete, standalone system that showcases Texas Instruments’ BQ25504 1-cell Li-Ion/Li-Pol IC. This multipurpose device can be used in a wide variety of applications and employs many features including an advanced, integrated system level protection circuit to protect the battery against overvoltage, undervoltage, overcurrent, thermal, and short circuit conditions. Application FieldThe BQ25504EVM-674 can be used for energy storage, mobile power applications, portable debug boards, and ultra-low power handheld applications. It helps extend battery life, increase protection, and improve system performance. The BQ25504EVM-674 also features an integrated 3.3-V/128-mA LDO regulator, which can be used to support additional components in the system or to supply power to a connected host system.The BQ25504EVM-674 also offers useful features such as the ability to measure battery voltage, current, and temperature. Its effective communication capability makes it suitable for remote system monitoring and diagnostics. The I2C bus connection allows for communication with a host processor where the user can set various parameters and exercising of safety functions, such as Vmax, Vmin, and protective features. Working PrincipleThe BQ25504EVM-674 works on the principle that the load will charge and discharge through the battery. When charging, the device transitions from a high-efficiency precharge stage to constant current and constant voltage stages. Depending on the input power, the device maximizes efficiency by automatically switching a synchronous rectified buck-boost DC/DC converter between buck (step-down) and boost (step-up) operating modes.The BQ25504EVM-674 also implements a protection circuit to protect the battery from overvoltage, undervoltage, overcurrent, thermal, and short circuit conditions. It includes an integrated voltage reference, serial interface, and linear regulator to ensure continuous voltage regulation while charging or discharging the battery.The BQ25504EVM-674 also includes a battery gas gauge controller, allowing the end system to accurately and efficiently measure the battery capacity by communicating with the battery. Additionally, the chip can be programmed to detect the presence of a charger and automatically control the charging current, providing the best possible performance while maintaining safety for the battery.ConclusionOverall, the BQ25504EVM-674 offers a complete and comprehensive solution for evaluation and demonstration of Texas Instruments’ BQ25504 1-cell Li-Ion/Li-Pol IC. It provides accurate measurements of battery voltage, current, and temperature, all while implementing a robust system-level protection circuit to protect the battery. The integrated LDO regulator is also ideal for supplying power to the additional components in the system, making the BQ25504EVM-674 a versatile solution to design projects.
