BQ25017RHLT TI Battery Charger IC | 20-VQFN (3.5x4.5) | 1A Charge, 4.2V

Product Overview

The BQ25017RHLT from Texas Instruments is a highly integrated, single-cell Li-Ion battery charger IC designed for space-constrained portable applications. It features a 1A charge current capability, a fixed 4.2V charge voltage, and operates from a 4.5V to 6.5V input supply. The device is housed in a compact 20-pin VQFN package (3.5mm x 4.5mm) with an exposed thermal pad for efficient heat dissipation. It includes power path management, allowing the system to be powered directly from the input while charging the battery, and supports USB-friendly charging with automatic input current limiting.
