The RT9511GQW is designed to be incorporated into battery charging and system protection circuits for notebook computers, tablets and smart phones. The IC operates from an input voltage range of 7V to 32V and provides an accurate and safe battery charging and cell protection for one or two series Li-ion/Li-polymer cells. It is available in 24-pin SSOP package.

Application Field of RT9511GQW

The RT9511GQW is a power management IC (PMIC) for battery chargers with advanced charging features, which is applied in battery charging and system protection circuits for notebook computers, tablets and smart phones. It is also applicable for various portable devices, such as digital cameras, MP3 players and PDAs.

The RT9511GQW offers a wide range of features to meet the needs of most battery charging applications. Its high input voltage range allows the system to be powered from sources beyond wall adaptors. The RT9511GQW also integrated advanced safety features to provide an extra layer of protection against battery over charging, short-circuiting or over temperature conditions.

The RT9511GQW also contains a low dropout linear regulator (LDO) for system supply during no load condition. This helps Notebooks Short Term Reference (NSTR) condition and improves the system battery life. As a PMIC for battery chargers, it has become firmly established in the market and has become a reliable solution for many application areas.

Working Principle of RT9511GQW

The RT9511GQW is designed to accurately detect the battery charge state and charge current, then terminates the charging process once the predetermined voltage level is reached. It also monitors the temperature of the battery stack and adjusts the charge current accordingly. During the charging process, the RT9511GQW monitors the battery voltage and constantly adjusts the charge current to maintain the voltage level.

The RT9511GQW also features programmable over charging protection. The over charging protection shuts down the charging process when the preset threshold is exceeded. This helps protect the battery from over charging due to error conditions or user abuse.

After the charge termination, the RT9511GQW still monitors the battery voltage and restarts the charging only when the voltage drops below the preset threshold. The RT9511GQW\'s multi top-off charging feature helps extend battery life by charging the battery with a smaller current. This helps reduce stress on the cells and prolong their life.

Conclusion

The RT9511GQW is an advanced power management IC (PMIC) for battery chargers. It is designed to accurately detect the battery charge state, monitor the temperature and adjust the charge current accordingly. The RT9511GQW also features programmable over charging protection to protect the battery from over charging. Additionally, its multi top-off charging feature helps extend battery life by charging the battery with a smaller current.

Thanks to its advanced features, the RT9511GQW has become the ideal power management IC for battery chargers in notebook computers, tablets, smart phones, digital cameras, MP3 players and PDAs. With its accurate and safe charging operation, the RT9511GQW is an integral part of PMIC - Battery Chargers.
