This article will discuss the DS2792G+T&R application field and working principle.

• DS2792G+T&R Application Field:

The DS2792G+T&R features an integrated supply regulator and dual switching regulators that make it ideal for a wide range of battery-powered applications. It can be used in applications such as: remote control devices, portable media players, digital video and photos, portable gaming systems, mobile/wireless devices, and digital cameras. Given its integrated power management and comprehensive battery protection features, the DS2792G+T&R is an ideal choice for portable products that require reliable power management, long battery life and maximum power efficiency.

• Working Principle:

The DS7292G+T&R uses a sophisticated battery management algorithm to monitor and control the charge and discharge of a battery. The power management IC (PMIC) integrates dual switching regulators, a linear regulator, a programmable voltage source, and a charge characteristics detection system in one. All these components enable the device to monitor the battery\'s status and adjust the charging current and voltage accordingly.When the device is connected to a battery and power source, the Dual Switching Regulators (DSRs) automatically begins charging the battery. The DSRs will adjust the charging current and voltage based on the battery\'s voltage, temperature and capacity. The Linear Regulator provides precise output voltage adjustment to the DS2792G+T&R and any other power management ICs connected to it. The programmable voltage source enables the device to supply different voltages to the battery based on the user-programmed requirements. The Charge Characteristics Detection System constantly monitors the battery status and determines its discharge current, temperature, and capacity. It then sends this information to the power management IC in order to adjust the charging parameters accordingly.

• Conclusion:

The DS2792G+T&R is a highly integrated and cost-effective PMIC developed by Maxim Integrated specifically for battery-powered applications. It offers superior protection for the system, advanced battery characterization and control algorithms, and a sophisticated battery management algorithm. This PMIC is an ideal choice for portable products that require reliable power management, long battery life and maximum power efficiency.
