Simplifying Battery Management Complexity with AccuCharge™
The drastic surge in personal electronic devices (PEDs) brought to the forefront many strengths but also weaknesses of rechargeable battery technologies, including Lithium ion and polymer. With safety being the top concern, every Lithium ion or polymer battery requires a safe charger, a comprehensive protector and an accurate fuel gauge. Small cells and fast charging parallel cells have especially stringent requirements due to the need for precise termination of charging and imbalanced charging, respectively. Adding to the stack of design challenges, poor fuel gauge accuracy can result in premature or abrupt system shutdown. Therefore, it is imperative to use a high-accuracy fuel gauge that indicates the state of the battery, and how much run-time is available. New battery management solutions address these complex challenges using the novel AccuCharge™ technology from Analog Devices. AccuCharge technology leverages the fuel gauge to control the integrated charger.
