Overview

The BQ24295RGER is a highly integrated 3A switch-mode battery charge management and system power path management device for single-cell Li-Ion and Li-polymer batteries. It features a synchronous PWM controller, high-accuracy current and voltage regulation, and a power path management system that allows the system to be powered while the battery is charging.

Why Choose This Part

The device offers a high 3A charging current with 0.5 percent voltage accuracy, ensuring fast and precise top-off for modern lithium chemistries. It significantly reduces BOM count by integrating the switching FETs and providing a low 5uA sleep current for extended shelf life.

Applications

Power Banks
Utilizes 3A fast charging and high-efficiency buck conversion to manage high-capacity cells in portable chargers.
Tablet and Smartphone Charging
Provides USB-compliant input current limiting and programmable charge parameters via I2C for mobile devices.
Portable Media Players
Ensures system stability with power path management that prioritizes system load over battery charging.
Industrial Handhelds
Operates across a wide temperature range of -40C to 85C with integrated fault protection for rugged environments.
