Texas Instruments BQ24272 2.5A, Singe Input, Single Cell Switchmode Li-Ion BATTERY CHARGER with Power Path Management BQ24272YFFT

The BQ24272YFFT 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 device to power the system while simultaneously charging the battery. This capability is particularly useful in applications where space is limited and high efficiency is required. The charger operates from a dedicated power source and includes thermal regulation protection, battery short-circuit protection, and a soft-start feature to minimize inrush current. The BQ24272YFFT supports a wide input voltage range of up to 20V, with over-voltage protection set at 10.5V. It is designed to maintain a minimum system voltage of 3.5V, enabling operation even with a deeply discharged or absent battery. The device incorporates an internal control loop that monitors temperature and adjusts the charge current accordingly to prevent overheating. Additionally, it includes a voltage-based thermistor monitoring input for safe battery temperature management. This product is available in a compact 49-ball WCSP package, making it suitable for applications such as handheld devices, portable media players, and tablets. The operating temperature range is from -40¬8C to 85¬8C, ensuring reliability in various environmental conditions.
