PMIC - Battery Chargers

The ISL6253HRZ is a lithium-ion/polymer battery charger IC, which is specifically designed to enable fast-rate charging of smartphone and tablet battery packs, while providing robust performance and safety features. With low external component count and fast charging capability, this integrated charger IC provides a complete solution for advanced portable applications. The ISL6253HRZ can be controlled by an I2C interface, enhanced by the Texas Instruments Green Point technology for extra power management efficiency, and is available in a 3mm x 3mm x 0.75mm MLF package.

Application Field

The ISL6253HRZ integrated charger can handle an input current of up to 4A for smartphone/tablet designs, and also supports a wide range of other portable applications including wearables, video cameras, Bluetooth headsets and many other consumer devices. By providing smooth power switching, the IC allows for a fast, efficient and reliable source of charging power. This battery charger is also suitable for applications requiring voltage-regulated charging and overvoltage protection. Additionally, due to its support for multiple battery chemistries, the ISL6253HRZ is able to cater to a wide range of different applications, while also meeting safety standards.

Working Principle

The ISL6253HRZ features an intelligent power IC controller as the core of its battery charging process. This IC contains three sensing amplifiers, which are used to measure the voltage, current and temperature of the charging battery. The IC then allows the charger to start and stop charging, as well as increase or decrease the output current. Furthermore, the IC supports integrated safety features, such as short-circuit protection, over-temperature protection, over-voltage protection and over-current protection.The IC also integrates a low voltage, low current reference and a voltage error amplifier, which are used to accurately regulate the charge voltage and current during the constant voltage and constant current stages of the battery charging cycle. This ensures that the charger is able to provide consistent and reliable charging.The charger is also temperature compensated, ensuring the battery is not over-heated during charging. The charger also supports low quiescent current, enabling the IC to monitor the battery status whilst in standby mode, meaning it can be safely used in portable applications.

Conclusion

The ISL6253HRZ is an integrated lithium-ion/polymer battery charger IC, which is specifically designed for fast rate charging of smartphones and tablet battery packs, while providing a robust and safe charging process. It has a wide range of application fields and supports a range of battery chemistries. The IC contains a variety of sensing and protection features, allowing for smooth, efficient and reliable charging. It also provides output voltage and current regulation, temperature compensation and low quiescent current. All of these features make the ISL6253HRZ a perfect choice for advanced portable applications.
