TPS2456EVM is a one-cell Lithium Ion (Li-ion) battery charger evaluation module (EVM) used to evaluate the characteristics of Texas Instruments TPS2456 battery charger. The integrated device monitors the state of a single Li-Ion battery cell, controlling safety features and charging/discharging parameters.

Evaluation and Demonstration Boards and Kits range from general-purpose evaluation boards to prototype boards and demonstration kits for a specific application. In the case of the TPS2456EVM, the EVM provides two different schematics and a set of test-points to evaluate and demonstrate the TPS2456.

The TPS2456EVM uses three integrated circuits, a TPS2456 battery charger that includes a supervised Li-Ion battery monitor and charging circuit, an MSP430 microcontroller, and an MSP430 based LED driver. The MSP430 microcontroller is used to control the TPS2456 and the LED driver based on the real-time conditions of the battery, as measured by the TSP2456.Through the configuration of the MSP430 microcontroller and by toggling a few switches, the users can quickly and easily modify the charging conditions to fit their exact requirements.

The TPS2456EVM includes several built-in features to maximize the user experience and performance. The user can measure the charging/discharging parameters of the Li-Ion battery, such as the output voltage and current levels, as well as the battery temperature. This allows the user to closely monitor the real-time performance of the TPS2456.

The EVM also provides two schematics to test the TPS2456. The first schematic is used to evaluate the single cell Li-Ion battery charge/discharge characteristics, while the second schematic allows the user to evaluate the TPS2456 performance in a multi-cell battery application. The second schematic allows the user to easily evaluate the capability of the TPS2456 to extend the battery life by charging multiple battery cells simultaneously with minimal stress and disruption to the other cells.

The TPS2456EVM also includes a few other features. For example, the user can measure the amount of energy stored in the battery and the amount of energy consumed/discharged from the battery by using the included energy metering circuit. This allows the user to accurately calculate the battery capacity, as well as to ensure the most efficient operation of the TSP2456.

Overall, the TPS2456EVM provides a comprehensive and easy-to-use platform to evaluate the functionalities of the TPS2456 battery charger. It allows the user to quickly and easily modify the charging parameters for their exact requirements, as well as measure various battery parameters through the on-board test points.
