Fault protection includes over-temperature and over-voltage shutdown, which saves the downstream BOM from needing a separate supervisor IC. ## Sourcing and package handling","metaTitle":"BQ24161YFFR – TI Li-Ion 1-Cell Charger, I²C, 2.5 A Max","metaDescription":"Texas Instruments BQ24161YFFR: active 1-cell Li-Ion/Polymer charger, I²C interface, 2.5 A max charge current, -40°C to 85°C, 49-DSBGA package.
