The DS2720AU+ is part of the PMIC - Battery Management catalog and is a robust, low-cost gas gauge solution with battery-pack integration features. It is able to measure the absolute state of charge (SOC) of the battery and predict accurate estimates of remaining capacity and run-time available in a safe, reliable, and efficient manner. The device’s integrated features, including equalization and safety timer, give designers the flexibility to create a complete battery management system with minimal external components. The DS2720AU+ integrates a 16-bit microcontroller core with a 3.2V level shifter for communication compatibility with 1.8V and 3.3V hosts. This device utilizes a Complimentary Gain Cell (CGC) algorithm that provides excellent divergence between the battery\'s actual content and its measured state of charge. This allows for a more accurate and reliable state of charge prediction and ensure that the battery pack remains within its safe operating window. The DS2720AU+ also includes integrated safety features that continuously monitor key voltage and temperature readings for safe pack performance. Its Equalization feature allows for balanced charging and discharging of individual cells when applicable and its safety timer feature can be configured to limit a charge cycle’s runtime. In addition to these features, the DS2720AU+ has a robust sleep mode feature that minimizes active power usage when the battery pack is not in use. The DS2720AU+ powers a wide variety of mobile devices and is ideal for applications such as travel adapters, laptop and cell phone battery packs, bluetooth headsets, digital cameras, and music players. Its accuracy makes it a great solution for gauging the remaining capacity of a battery pack and predicting the remaining life of the battery so users know how much power they have left and when it is time to recharge. Since the DS2720AU+ device contains all the required components for a complete battery management solution, designers can implement solutions with fewer components and expand their design options. The 16-bit microcontroller reduces the overall cost of the system, and the safety timer and equalization features maintain optimal battery pack performance. Overall, the DS2720AU+ is a great value for battery management applications, as it incorporates all the necessary components for a full-featured battery management system. Its accuracy, integration, and robust safety features give designers the options they need to create cost-effective and reliable solutions.
