Texas Instruments BQ24272 2.5A, Singe Input, Single Cell Switchmode Li-Ion BATTERY CHARGER with Power Path Management BQ24272RGER

The BQ24272RGER is a highly integrated single-cell Li-Ion battery charger designed for portable applications, capable of delivering a charge rate of up to 2.5A. It features power path management, allowing the system to operate from a DC power source while simultaneously charging the battery. The device supports a wide input voltage range of up to 20V and includes over-voltage protection (OVP) at 10.5V. This charger employs a three-phase charging process: conditioning, constant current, and constant voltage, ensuring efficient battery management. It includes thermal regulation protection and a soft-start feature to minimize inrush current. The BQ24272RGER also provides battery short-circuit protection and can instantly power the system from a deeply discharged or absent battery, maintaining a minimum system voltage of 3.5V. The device is available in a compact QFN package, making it suitable for space-constrained designs. It is ideal for applications such as handheld products, portable media players, and tablets, where efficient battery management and compact size are critical.
