Evaluation and Demonstration Boards and Kits provide a great way to understand a complex system. One example is the BQ24750EVM from Texas Instruments (TI). This powerful evaluation module is designed to evaluate the performance of the BQ24750 single-cell 1s Li-Ion fast-charging system solution. The BQ24750EVM features several innovative features that make it ideal for testing and evaluation. In this article, we will explore the application field and working principle of the BQ24750EVM.

The application field of the BQ24750EVM is wide and varied. It can be used to evaluate battery pack systems for high-end consumer, industrial, medical, and automotive uses. It is also suitable for evaluating multiple-cell applications such as cell balancing, boost/reverse boost converter designs, and buck-boost converter designs. This makes it ideal for studying the principles of pulsed charging, constant current operation, LED control, and much more.

The working principle of the BQ24750EVM is fairly simple. It is based on the single board design of the BQ24750. This device is a dual MOSFET synchronous buck-boost converter with a high-performance current mode boost controller. It has integrated integrated point-of-load and system-level control circuitry, enabling the device to switch quickly between different charging modes. The device also has a programmable charging state machine, which can be used to alter the current and voltage settings depending on the battery conditions.

In addition, the BQ24750EVM provides the user with an intuitive graphical user interface (GUI) for the evaluation. It enables the user to preset the voltage and current settings, as well as monitor the status of the battery and the charging cycle. Furthermore, the onboard I2C interface is controlled on the system by a simple serial interface. This allows the user to control the device remotely. The BQ24750EVM also includes several safety features, such as temperature monitoring and charging fault detection, which make it suitable for use with both single-cell and multiple cells.

The BQ24750EVM is an excellent device for the evaluation of advanced power management solutions. It is easy to use, provides great performance, and is highly configurable. With the wide application field and easy-to-use graphical user interface, it is perfect for evaluation and demonstration of the BQ24750.
