DS2776G+T&R application field and working principleThe DS2776G+T&R is a Battery Monitoring and Protection IC from Maxim Integrated. It is designed for use in Medium to High Capacity Lithium-Ion battery packs. The main purpose of the DS2776G+T&R is to measure and monitor the voltage, current, temperature, and charge state of the battery, and then to protect the battery from overvoltage, overtemperature, and overcharge conditions. The DS2776G+T&R is divided into two main parts: the Battery Monitor and the Battery Protection IC. The Battery Monitor IC measures the voltage and current at the battery terminals, and then communicates with the Battery Protection IC to determine the state of charge, temperature, and other operational parameters of the battery. The Battery Protection IC uses this information to provide protection against overcharge and overvoltage conditions, as well as protection against overtemperature by shutting down the battery in extreme cases.The Battery Monitor IC also monitors the NTC thermistor in the battery pack, and can shut down the battery if the temperature exceeds a certain limit set by the user. The DS2776G+T&R also features a programmable battery current limit that can be used to limit the amount of current that flows through the battery in order to prevent overcharge conditions. The DS2776G+T&R can also be used for dual battery systems, allowing the user to monitor and protect two separate batteries.The DS2776G+T&R can be used in a variety of applications including electric vehicles, electric bicycles, portable electronics, and energy storage systems. It has a wide variety of features that make it suitable for a wide range of applications, including a wide operating temperature range, a wide operating voltage range, battery current sense resolution, and cell over-voltage protection.In summary, the DS2776G+T&R is a versatile and powerful battery monitoring and protection IC designed to provide safety, cost savings, and overall battery life improvements. It is designed to provide protection against overvoltage, overtemperature, and overcharge conditions, and to provide efficient monitoring and protection of battery packs. It is a reliable and cost-effective solution for medium to high capacity lithium-ion battery packs.
