Communication with the host processor runs over an I²C interface, so the charge current, termination voltage, and safety timers can be tuned in firmware rather than with external resistors. This is the same control scheme used across TI's I²C-charger family; the BQ25871 sits as the high-current option for single-cell designs. ## Fault protection that saves the BOM The IC integrates overcurrent, overtemperature, overvoltage, and reverse-current protection. That means the charger itself handles the safety monitoring — no separate supervisor IC or external comparator needed on the charge path. For a procurement buyer, this collapses the BOM count around the charger and reduces qualification effort. If your device lives in a hot enclosure or sees outdoor exposure, the charger's thermal regulation loop will back off the charge current before the die hits the overtemperature threshold, keeping the system running without a hard shutdown. ## Active production and compliance The base product number BQ25871 covers the family; the YFFT suffix denotes the 42-DSBGA package and tape-and-reel / cut-tape delivery.","metaTitle":"BQ25871YFFT Li-Ion Charger IC, 7A Max, I²C, 42-DSBGA","metaDescription":"Texas Instruments BQ25871YFFT single-cell Li-Ion battery charger IC. 7A max charge current, I²C control, fault protection.
