The BQ24620EVM is an evaluation module for testing the performance of a highly integrated switch-mode Li-Ion battery charging controller developed by Texas Instruments. The evaluation board is designed to demonstrate the capabilities of the BQ24620, a single minute chip containing a high performance linear charger, a dual MOSFET synchronous buck converter and a power path switch. The combination of these three functions provides a high performance, power-efficient solution for single cell Li-Ion and Li-Polymer battery charging applications.

The main purpose of the evaluation module is to provide an environment where the performance of the BQ24620 can be evaluated, tested and verified. It is a versatile platform for evaluation and development purposes, and with its wide range of features, it is well positioned for use in a variety of applications.

The main features of the BQ24620EVM include two isolated test points for measuring the current and voltage output from the IC, a DC power supply input connector, two LED indicators for charging status, and an analog current sense. In addition, the board includes eight control and monitoring functions, temperature signal conditioning, and fault detection for overvoltage, current, and temperature.

The board also includes a USB connector and a PC GUI software which interfaces with the BQ24620IC allowing for easy configuration and monitoring of the device. The GUI can be used to control the operation of the IC, such as setting the charge current and adjusting the charging timer, as well as viewing the current, voltage and charger status in real time.

The main working principle of the board is based on the use of the BQ24620IC, which controls the charging of a single cell Li-Ion/Li-Polymer battery. The IC monitors the voltage and current of the battery pack and will adjust the switching frequency to optimize the power transfer from the charger to the battery. It also provides temperature monitoring and protection using an internal fixed-threshold thermal sensing circuit. Once the battery has charged to the specified voltage, the IC will terminate the charging operation.

In sum, the BQ24620EVM is a versatile evaluation board designed to evaluate and demonstrate the capabilities of the BQ24620 single-chip Li-Ion battery charging controller. With its comprehensive control and monitoring functions, the board provides an ideal platform for developers to test the performance of the IC and optimize their systems for a variety of applications.
