It handles charge currents up to 2.5A and communicates over an I²C interface for programmable charge parameters. The 2.5A max charge current is the headline number that determines how fast a single-cell Li-Ion pack (nominal 3.7V) can be replenished. For a 2500 mAh cell, that is roughly a 1C rate — a full charge in about an hour, assuming the input supply can deliver the power. The 6V max supply voltage means this part is designed for 5V USB or regulated 5V rails, not for direct connection to a 2-cell pack or a 12V input. If your system runs from a higher-voltage bus, you will need a separate step-down stage ahead of this charger. Built-in fault protection covers over-temperature and over-voltage conditions, which is a practical safety net when the charger is embedded in a sealed enclosure or operates in a warm ambient. The I²C interface allows the host microcontroller to read fault flags and adjust the charge current dynamically — useful for thermal throttling or for matching the charge rate to the available input current from a USB source. The 49-DSBGA (2.8x2.8 mm) is a fine-pitch BGA with no exposed thermal pad — all heat dissipation goes through the solder balls and PCB copper. Without that via stitch, the junction temperature rises quickly above 2A continuous charge current. The package is surface-mount only, and the shipping options include Tape & Reel and Cut Tape.","metaTitle":"BQ24168YFFT Li-Ion Battery Charger IC, 2.5A, 49-DSBGA","metaDescription":"Texas Instruments BQ24168YFFT single-cell Li-Ion/Li-Pol charger IC with I²C interface, 2.5A max charge current, -40°C to 85°C range.
