Evaluation and Demonstration Boards and Kits are essential for electrical engineers, allowing them to easily prototype a wide variety of circuit designs. The BQ25895EVM-664 is one such evaluation and demonstration board, and it offers a powerful range of features that allow for advanced circuitry and testing.
The BQ25895EVM-664 is an advanced, integrated power management solution designed for high-power and/or portable application systems. It is suitable for areas such as communication technology, automotive power, and industrial circuits. This integrated solution enables a rapid development of products, providing features such as charging control, system management, and using only a few external components.
The EVM consists of the BQ25895-Q1 charging IC, a buck-boost power converter, and various other components. The charging IC contains a wide range of integrated components such as synchronous buck PWM controller, synchronous buck-boost PWM controller, load switch, power detection, current-sense amplifier, current-source circuit, and two current-limiting interfaces. This allows for a range of power management features without requiring multiple additional parts. It also includes a 7-channel coincident-current-limit device, which can prevent high levels of output current during shorting events.
The integrated buck-boost converter provides efficient power delivery over a range of input voltages. The converter can operate in either continuous current or discontinuous current mode for better efficiency and power density. Additionally, the synchronous PWM control used in the buck-boost converter, together with the integrated current sensing, allows for fast and precise control of the output current. The EVM also features an integrated current-source circuit that can be used as either a constant-current source or constant-voltage source.
In addition, the EVM includes over-voltage/over-current protection, thermal protection, and a status indicator LED, which help ensure safe operation. The entire EVM is configured to meet the requirements of safety standards such as UL, CSA, and EN, making it suitable for applications where stringent safety requirements must be met.
The BQ25895EVM-664 evaluation board can be used for a wide range of power management and testing applications. It is particularly well-suited for applications that require flexibility, efficient power delivery, and accurate control of both the input and output power. As such, the tool is especially useful in the development of portable electronic applications, portable medical devices, and automotive accessories.
Overall, the BQ25895EVM-664 is an essential evaluation and demonstration tool for engineers of all skill levels. It offers a powerful range of features, making it suitable for a wide range of circuit designs. The integrated components and protection features make it easy to develop reliable and safe solutions, helping engineers quickly bring their projects from concept to completion.
