Maxim Integrated DS2761AX-025/TR High-Precision Li+ Battery Monitor

The DS2761AX-025/TR from Maxim Integrated is a sophisticated high-precision lithium-ion (Li+) battery monitor that offers a comprehensive solution for battery management in portable devices. This small, power-packed component is designed to ensure the safe and efficient operation of rechargeable Li+ battery packs, which are critical to the performance and longevity of modern electronic devices.

The DS2761AX-025/TR provides a multitude of features that make it essential for battery monitoring. It includes high-precision measurements of voltage, temperature, current, and accumulated charge, allowing for precise battery capacity monitoring and prediction of remaining battery life. This data is crucial for devices that require reliable battery status information to manage power consumption effectively.

One of the standout features of the DS2761AX-025/TR is its ability to perform on-chip temperature measurements, which is vital for maintaining battery health. Overheating can lead to reduced battery life or even pose safety risks, making temperature monitoring a key aspect of battery management systems.

Additionally, the chip supports 16-bit current measurement, which enables it to detect very small changes in battery discharge rates. This high resolution is particularly beneficial for applications that need to extend battery life as much as possible, such as medical devices, wearables, and other portable electronics.

With its programmable current accumulation, the DS2761AX-025/TR allows for precise tracking of the amount of charge entering and leaving the battery. This feature aids in calculating the battery's state-of-charge (SOC) and state-of-health (SOH), providing essential information for battery maintenance and replacement scheduling.

Moreover, the device comes in a compact, surface-mount package, the Tape and Reel (TR) format, which facilitates automated assembly processes, making it an ideal choice for mass production. Its small footprint and high integration level help reduce the overall size of the battery management system, enabling sleeker and more compact device designs.

In summary, the DS2761AX-025/TR is a versatile, high-precision battery monitor that offers critical features for advanced battery management. Its ability to provide detailed battery metrics ensures that portable devices operate safely and efficiently, maximizing battery life and performance.
