PMIC - Battery Chargers have numerous applications in various consumer electronics and the BQ24113ARHLR is no exception. The BQ24113ARHLR is a highly integrated, single-stage battery charger for thermal, mechanical, and electrical stress due to its advanced control system, DC/DC converter architecture, circuit protection and built-in power path management. This high-efficiency, multi-mode architecture results in low power dissipation and is ideal for applications that require minimal power consumption.

The BQ24113ARHLR is custom designed for single-cell Li-ion and Li-polymer battery packs ranging from 4.2 to 32V. It is designed to offer a high level of programmability and features a wide range of power profiles, user adjustable input current limit and charge termination current. With its advanced battery charging algorithm and wide range of over voltage and over current protection, it is suitable for a variety of battery charging applications such as laptop and smartphone chargers.

The BQ24113ARHLR is a single-stage, pulse-width modulation (PWM) based switching charger that measures the battery voltage and temperature in order to charge the battery safely and cost-effectively. It is powered through an average current-limited pseudo-constant voltage (CV) regulator, which helps to minimize power dissipation and thus increases the overall efficiency. Furthermore, the CV regulator provides charging current regulation, enabling the BQ24113ARHLR to charge the battery efficiently without over charging or over discharging.

Through its integrated power path management, the BQ24113ARHLR provides instantaneous charging current of up to 6A and simultaneously transfers power from the mains supply, battery or both sources for ultimate protection against over discharge and extended battery life. On top of that, it also features an accurate CC/CV line regulation that eliminates power-line disturbances, and is specifically designed to control the charge transfer current of battery packs with traces in two directions, ensuring the battery receives the correct charge and battery safety is always maintained.

The BQ24113ARHLR is an ideal battery charger for many consumer electronics such as laptop and smartphone chargers as it offers high efficiency performance with low power dissipation and a wide range of features. It is designed to sense, control and regulate the power received from the power source during battery charging. It is a single-stage PWM based switching charger that is both cost-effective and highly reliable.

Finally, the BQ24113ARHLR is extremely user friendly, with its digital diagnostic functions and ability to conduct self-testing on the battery for charging accuracy. Thanks to its advanced control system, DC/DC converter architecture, circuit protection, and built-in power path management, the BQ24113ARHLR is a convenient, sophisticated and cost-efficient way to charge a variety of single-cell Li-ion and Li-polymer battery packs.
