DS2788E+ Application Field and Working Principle

The DS2788E+ is a high-performance,cutting-edge solution for advanced battery management applications that measures and monitors battery temperature and voltage, as well as controlling and protecting Li-ion/ Li-polymer batteries. Thanks to its Industry-leading features and improved performance, the DS2788E+ is ideal for applications such as digital cameras, mobile devices, and handsets.

The DS2788E+ is the next generation of low-power, multi-channel battery management solutions. The DS2788E+ offers a variety of features to enhance performance and battery life, including an autonomic power down mode that reduces quiescent current and adaptive live-deadline system that prevents unnecessary shutdowns. The DS2788E+ uses a patented power supply filter circuit to enable it to accurately detect battery voltage, while eliminating any power spikes. It also includes a load control circuit that can be used to effectively manage its power distribution across the battery, allowing more efficient use of its energy.

The DS2788E+ is designed for use with a wide range of Li-ion and Li-polymer chemistries, including Lithium Cobalt Oxide (LCO), LiNCO, LiMO, and LiFePO. The DS2788E+ also features a secondary temperature monitoring capability, which is useful for operating in cold environments where battery temperature can play a significant role in performance.

The DS2788E+ utilizes a variety of integrated components and sophisticated algorithms to ensure accurate sensing and precise digital control over battery charging and discharging. It offers three-state battery management, which provides an additional layer of protection by guarding against thermal runaway and overcharging. In addition, the DS2788E+ includes a unique wake-up circuit that can drastically reduce the time it takes to wake-up a device from sleep mode.

When it comes to performance, the DS2788E+ provides one of the highest accuracies of any Li-ion battery management solution. Its proprietary predictive algorithm repeatedly readjusts thresholds in real time with minimal power drain, resulting in increased capacity for safety margin, faster device wake-up, and more efficient overall battery utilization. The DS2788E+ also features an advanced power protection circuit that can limit output current if it exceeds a specified ceiling. This ensures that the battery is always protected from overcharging or discharging, helping to extend its overall life.

The DS2788E+ also provides excellent supporting features for battery monitoring, such as auto-adjusting VBAT offset compensation and AutoCellDrain for leakless battery testing. Additionally, it supports several over-the-air (OTA) programming capabilities, allowing the device to be controlled remotely and modified as needed. Battery diagnosis and troubleshooting can also be handled remotely, with support for online or offline debugging over USB.

Due to its advanced features, efficient design, and reliable performance, the DS2788E+ is an ideal solution for any Li-ion/ Li-polymer battery management application, as well as digital cameras, mobile devices, and handsets. It offers excellent performance at low power and is designed to minimize device wake-up time, maximize capacity, and ensure safety and reliability. In short, the DS2788E+ provides an excellent platform for advanced battery management.
