The BQ24045EVM (Evaluation Module) is a specialized board designed for the evaluation and demonstration of the BQ24045 devices, a highly integrated, proprietary battery charger controller for single-cell Li-ion (Lithium-Ion) battery packs. With a tiny footprint, the BQ24045EVM is ideal for developing applications such as wearable devices, digital cameras, and cell phones.

The BQ24045EVM consists of a tiny circuit board that connects to an external 5.25V / 7.5V power supply. It features integrated battery-charging control, current regulation, and fault-reporting capabilities. The board also has an adjustable setpoint programming feature that allows users to adjust the charge current levels from 0.1A to 1.6A. The board also features a built-in LED indicator that clearly shows the current charging state, as well as connection verification.

The BQ24045EVM’s power and charging capability are derived from two main components; the system configuration microcontroller and the linear charger. The system configuration microcontroller is responsible for monitoring the input power and adjusting the output charge voltage and current according to the user’s desired parameters. The linear charger uses an extension board to control its output charging current. It operates from an open circuit voltage of 5.25V to 5.50V, and can provide up to 1.6A of charging current to its connected battery.

The EVM board also comes with a user-friendly software features, including status monitoring, accuracy settings, and a built-in troubleshooting guide. The software provides a real-time status indication of the device’s charging status, as well as a monitoring feature for current, voltage, temperature, and current monitoring. Additionally, it offers both an accuracy adjuster and a feature to balance the battery’s charge/discharge cycle to ensure optimal performance. It also includes a built-in troubleshooting guide to help users quickly address any issues that may arise.

The BQ24045EVM evaluation and demonstration board is designed to provide users with a complete system to evaluate and understand the performance and capabilities of the BQ24045 battery charger controller. With its advanced features and intuitive user interface, the EVM is the perfect platform for exploring the potential of BQ24045 solutions.
