Modern technology has evolved the way we use and interact with the world around us. Whether it\'s smart phones, laptops, tablets, or any other electronic device, they all require an adequate and reliable power source. The Texas Instruments BQ25708RSNR is a highly efficient, low quiescent current, single-chip switch mode Li-ion battery charger controller IC that provides power from USB sources, adapters, wall outlets, or other power sources with standard USB figures.

This TI battery charger is a highly efficient step-down (buck) solution for charging single cell Li-ion batteries with very low quiescent current and high integrated current sensing and control with great performance. It also provides a wide variety of charging capabilities, including automatic recognition and negotiation with the USB power source type C and PD, and it also has a power delivery and fast charging protocol. All these charge control features make the BQ25708RSNR a prime choice for battery charging applications in Li-ion batteries such as cell phones, laptops, tablets and other devices.

The BQ25708RSNR has a wide operating temperature range of -40°C to +85°C and comes in a miniature 2.2mm x 2.0mm 16-pin wafer level package (WLP) which helps improve the PCB layout and reduce space and cost. The total current rating of the IC is 2.5A which is suitable for fast charging applications, and it also has a maximum charge current of 1.5A.

When it comes to working principle, the BQ25708RSNR is a dynamically voltage regulated charge controller with a buck controller, reverse current protection and current monitor. The buck controller allows it to maintain a constant output voltage from the power source, such as a USB source or an adapter, when charging the battery. The reverse current protection prevents the battery from discharging when it is not needed. The current monitor helps to regulate the charge current and avoid possible overcharge.

The BQ25708RSNR also has several safety features for protecting the battery and the system which include overvoltage protection, overcharge protection, over-discharge protection, and thermal overload protection. These features make the BQ25708RSNR a safe, yet easy to use, device for Li-ion batter charging applications.

In conclusion, the BQ25708RSNR is a highly reliable and efficient Li-ion battery charger IC from TI that can help you make your devices more power efficient and cost effective. With its wide range of features, it is easily one of the most sought after options for Li-ion battery charging applications. Not only does it come with built-in safety features for multiple levels of protection, but it also regulates the output voltage consistently, helping to ensure reliable power performance.
