MAX17075GTG/V+ belongs to the power management integrated circuits (PMICs) family, specialized power management series. It is a small, low-cost single-cell Li-ion and Li-polymer fuel gauge for portable applications. The chip integrates critical power management functions, such as AC-DC power conversion, voltage regulation, battery current measurement, and temperature management. The goal of the chip is to provide reliable, accurate and fast fuel gauge readings to the system.

The application field of MAX17075GTG/V+ mainly focus on portable electronic products, such as laptops, wireless earphones, mobile phones and tablets. The many featured applications use Li-ion or Li-polymer rechargeable batteries. CAPEPMIC-powered products have been developed with the newest version of the MAX17075 GTG/V+ chip and platform. A power conversion die and a small controller with a fuel gauge driver are integrated into the chip for a complete AC/DC power management platform. This platform allows designers to quickly deploy a high-performance power management solution.

The basic working principle of MAX17075GTG/V+ can be broken down into two basic categories, reading and charging process. During reading, the chip uses a voltage-based fuel gauge algorithm that monitors the cell voltage and measures the amount of charge inside the battery. By measuring the amount of charge, it can estimate the remaining battery life. During the charging process, the chip is responsible for the voltage regulation and current monitoring during the charging cycle. This helps to ensure that the battery is getting the correct amount of current and ensures the battery is not overcharged. In addition, the chip includes a temperature sensor to ensure the battery operates in a safe temperature range.

MAX17075GTG/V+ has become a popular choice for many power management design projects, because of its low-cost, small size and easy integration, which cuts down the overall design and manufacturing effort. The chip also offers safe and reliable Li-ion and Li-polymer battery management. Its high performance algorithms allow extensive estimates of remaining battery life, enabling more accurate prediction and more efficient use of the battery. In addition, its temperature monitoring feature provides a safe and secure operating temperature range for the battery, which can further extend the lifetime. Furthermore, advanced power conversion strategies give designers the ability to extend battery life in low-power applications and enable high-power designs. All these features combined make MAX17075GTG/V+ an ideal choice for many power management applications in a variety of portable electronics products.
