DS2764BE+ High-Precision Li+ Battery Monitor

The DS2764BE+ from Maxim Integrated is a comprehensive solution designed to monitor the state-of-charge and health of lithium-ion (Li+) batteries. This high-precision battery monitor is a key component in portable devices, ensuring that the battery operates within its safe limits and prolonging its lifespan.

With its integrated measurement features, the DS2764BE+ provides real-time tracking of various critical parameters. It measures voltage, temperature, current, and accumulated charge, delivering precise data to the system for effective battery management. The voltage measurement range is broad, accommodating various Li+ chemistries, and the temperature readings are essential for maintaining battery safety and performance.

Current measurement is another standout feature of the DS2764BE+. It utilizes a sense resistor to monitor the charge and discharge activity accurately, allowing for precise control over the battery's state-of-charge. This is particularly important for applications where battery longevity and reliability are paramount.

The accumulated charge tracking, or coulomb counting, provides an exact record of the charge entering and leaving the battery. This data is crucial for calculating the battery's state-of-charge and predicting its remaining capacity, which can help prevent unexpected shutdowns and extend the battery's usable life.

The DS2764BE+ also offers nonvolatile (NV) memory for data storage, which ensures that critical battery parameters are retained even when the system is powered down. This feature enables devices to maintain an accurate battery history and supports intelligent battery management strategies.

With its small footprint and low power consumption, the DS2764BE+ is an ideal choice for space-constrained portable applications. Its high level of integration simplifies design and reduces the need for additional components, making it a cost-effective solution for advanced battery management systems.

Overall, the DS2764BE+ provides a robust set of features for precise battery monitoring, enhancing the performance and safety of Li+ battery-powered devices. Its capabilities make it suitable for a wide range of applications, from smartphones and laptops to power tools and electric vehicles.
