That 2.5 A ceiling means a 2000 mAh cell can charge from empty in under an hour, assuming the input supply can sustain the power. The charger integrates over-temperature, over-voltage, and short-circuit fault protection, reducing the external protection components a discrete charger would need. ## Supply range and input source flexibility The device accepts a supply voltage up to 10 V max, which covers USB VBUS (5 V nominal), 5 V wall adapters, and higher-voltage sources like 9 V or 12 V supplies as long as the input stays below the absolute maximum. The wide input range gives the designer headroom to use the same charger across multiple product variants with different input sources, without changing the charger IC. ## Package and thermal consideration The 4x4 mm footprint suits compact handheld and portable devices where board space is tight.","metaTitle":"TI BQ24278RGER Li-Ion Battery Charger, 2.5 A Max, 24-VQFN","metaDescription":"Texas Instruments BQ24278RGER single-cell Li-Ion charger, 2.5 A max charge current, 10 V max supply, 24-VQFN (4x4 mm).
