Evaluation and Demonstration Boards and Kits are important tools for engineers who need to evaluate the performance of various components. The BQ24741EVM is one such board/kit, designed to evaluate the operation of BQ24741 Smart Battery Saver IC.

The BQ24741EVM is a single-cell Li-Ion/Li-Pol battery charger. It has two charging inputs – USB and AC adapter – that can be used for charging a device with one cell battery, while providing accurate and dependable charge current control. The board’s power management capabilities envision the development of more efficient charging strategies. It also provides system-level protection (OTP, OVP, battery detection circuit) and accurate charge status.

The BQ24741EVM is used in portable applications such as smartphones, satellite systems, vehicle navigation systems and medical equipment. It also has application in wearable and industrial products. It is proven to reduce the charge time by as much as 20% for single-cell Li-Ion/Li-Pol batteries. It can support a maximum charging current of 2A, making it suitable for high power applications.

The working principle of the BQ24741EVM is centered around Smart Battery Saver IC, BQ24741, which has a preset safety and power saving functions that can detect battery temperature, charge voltage, current, etc. The BQ24741 has time-based fast-charge control, allowing for rapid charge of the battery. It also detects the presence or absence of an external charger and adjusts the charge current accordingly. When the battery voltage falls below the charging threshold, the charger will resume charging the battery.

The board also includes two USB Type-A ports that allow for charging multiple devices in parallel, thereby reducing the system charge time. It also has an AC adapter inputs and a USB input that allows for both AC adapter and USB charging.

The BQ24741EVM is designed for quick and accurate evaluation of the BQ24741 Smart Battery Saver IC. It is a powerful tool for any engineer who needs to evaluate the performance of a BQ24741 IC. It is easy to set up and use, and provides an effective environment for developing, testing and validating applications involving BQ24741 Bluetooth ICs and related components.
