Maximum charge current is 1.5 A, set via the I²C bus, which lets firmware adapt the charging rate to battery capacity or thermal conditions without a board spin. ## 1.5 A charge current — what it means for charge time and thermals At 1.5 A max, a typical 1500 mAh single-cell Li-Ion pack charges in about an hour from flat, assuming the input supply can deliver the power. ## Industrial temperature range and protection On-chip fault protection covers over-temperature, over-voltage, and short-circuit, so the charger can survive a bad battery connection or a stalled fan without external clamp diodes. The BQ24271 base product number is current; TI has not announced an EOL or successor for this part.","metaTitle":"BQ24271RGER I²C Li-Ion Charger, 1.5A Max, 24-VQFN","metaDescription":"Texas Instruments BQ24271RGER single-cell Li-Ion charger, I²C programmable current up to 1.5A, -40 to 85°C, 24-VQFN.
