DS2775G+T&R

With the continuous advancement of technology, there is an increasing demand for advanced power management and battery management systems, which are essential for improving the performance and longevity of devices. The DS2775G+T&R integrated circuit, or IC, is a dual-channel, high performance and thermally-protected battery monitor and charger, designed to monitor and maintain devices powered by a single cell Lithium-Ion battery. The DS2775G is part of Texas Instrument’s line of power management and battery management ICs.

DS2775G+T&R Application Field

The DS2775G+T&R IC is a popular choice for many industrial and consumer applications, due to its flexibility and high performance. This IC is typically used for mobile products, such as portable navigation and storage device systems, ultrabooks, gaming handhelds, and wearables. Additionally, the IC can be used in low power industrial control systems, as well as in automotive, telecommunication, and medical applications.

DS2775G+T&R Working Principle

The DS2775G+T&R IC uses a balanced double-channel structure for maximum accuracy. A unique large dynamic “bi-modulus” voltage sensing technology, along with a proprietary analog-to-digital converter, is implemented to more accurately measure and regulate the charge/discharge of the battery. The device also features a low power consumption current sense and feedback control loop, to ensure energy efficiency and improved battery life.

The power management and battery management of the IC is further enhanced with self-contained, programmable gain and temperature compensation system, known as the Charge Wizzard™ agnostic architecture. This system allows the IC to accurately monitor and regulate the charge/discharge of the battery under various operating temperature conditions. In addition, the DS2775G+T&R offers a multiple protection feature, which includes overcurrent protection, overtemperature protection, and undervoltage lockout, in order to prevent potential system failures.

The DS2775G+T&R IC also offers multiple programmable parameters, including the charge/discharge current threshold, battery cut-off voltage level, charging modes, discharge time-out, and battery’s temperature margin. This allows system designers to easily configure the IC according to their specific needs. In addition, the IC is available in a variety of packages, such as LLP, QFN, SOIC, TFN, and SMT, which enables flexible PCB design options.

Conclusion

The DS2775G+T&R is a dual-channel, high performance, thermally-protected battery monitor and charger, which is designed for use in mobile products and industrial control systems. This advanced IC features an accurate voltage sensing technology, low power consumption current sense and feedback control loop, complete programmable parameters, and multiple protection features, to ensure reliable performance and long battery life.
