series introduction
The **DS2781 Series** is a family of advanced battery fuel gauge and protection ICs designed to provide accurate monitoring and management of single-cell lithium-ion (Li-ion) and lithium-polymer (LiPo) batteries. These devices are engineered to deliver precise measurements of battery voltage, current, temperature, and remaining capacity, ensuring optimal performance and safety in portable electronic applications. With its integrated features and robust design, the DS2781 Series is a reliable solution for extending battery life and enhancing system efficiency.
One of the key features of the DS2781 Series is its high-accuracy current measurement capability, achieved through an integrated sense resistor and low-offset analog-to-digital converter (ADC). This allows for real-time monitoring of charge and discharge currents, enabling precise calculation of the battery’s state of charge (SOC) and remaining capacity. Additionally, the series incorporates a temperature sensor to monitor battery conditions, ensuring safe operation by preventing overcharging, over-discharging, and overheating. The device also supports programmable protection thresholds, providing flexibility to tailor the system to specific battery chemistries and application requirements.
The DS2781 Series is designed with a compact and efficient architecture, making it suitable for space-constrained applications. Its low power consumption ensures minimal impact on battery life, while its I2C interface facilitates seamless communication with host systems for data logging and control. The series is also equipped with non-volatile memory to store critical parameters, ensuring data retention even during power loss.
Typical applications for the DS2781 Series include smartphones, tablets, portable medical devices, and other battery-powered consumer electronics. It is also widely used in industrial and automotive systems where reliable battery management is essential. By providing accurate fuel gauging and robust protection features, the DS2781 Series helps optimize battery performance, enhance safety, and extend the operational life of portable devices. Its versatility and reliability make it a preferred choice for engineers designing advanced battery management systems.
