A buyer with an active BOM slot should secure the estimated lifetime requirement in a single procurement action to avoid a mid-production EOL event. ## 1.25 A charge current, I²C programmable The BQ24151 is a single-cell linear charger for Li-Ion and Li-Polymer packs, delivering up to 1.25 A of programmable charge current from a supply rail rated to 6 V max. The charge current, termination voltage, and safety timer are all set over the I²C interface — no external resistor dividers needed for the basic profile, which saves two passives per BOM line. Battery pack voltage is capped at 4.44 V max. The IC integrates over-temperature and over-voltage fault protection. ## 20-DSBGA — footprint and process constraints The 20-DSBGA package demands a controlled PCB fabrication process — solder-mask-defined pads, microvia-capable stack-up, and a stencil aperture sized for the ball geometry. ## -40 to 85 °C — industrial portable use The linear topology means the pass element dissipates (Vin - Vbat) × Icharge as heat — at 1.25 A from a 5 V supply into a 3.7 V cell, the die dissipates about 1.6 W, which the DSBGA's thermal pad must sink to a copper plane.","metaTitle":"TI BQ24151AYFFR Li-Ion Charger IC, 1.25A, I²C, NRND","metaDescription":"Texas Instruments BQ24151AYFFR single-cell Li-Ion/Polymer charger IC. 1.25 A max charge current, I²C programmable, 20-DSBGA.
