It uses an I²C interface to program the charge current, so the host MCU can adjust the rate without swapping a set-resistor — useful when the same board must charge from USB, a 5 V wall adapter, or a 9 V supply. ## Why the 2 A ceiling and 10.5 V input matter on the BOM The 2 A max charge current sets the thermal budget for the 24-VQFN (4x4 mm) exposed-pad package. At full current the die-to-ambient temperature rise depends on the PCB copper area under the pad — a 2-layer board with a 1-inch² pour keeps the junction below the 125°C limit; a tight layout needs a thermal via array to the ground plane. The 10.5 V input ceiling covers 5 V USB and 9 V quick-charge adapters but not 12 V rails — a 12 V input exceeds the abs-max and kills the part on first plug-in. Fault protection is on-die: over-current, over-temperature, and over-voltage shut down the pass FET without an external fuse or supervisor. That saves a PTC and a comparator on the BOM — worth factoring into the board-area budget.","metaTitle":"BQ24250RGET TI Li-Ion Charger, I²C, 2A Max, 24-VQFN","metaDescription":"BQ24250RGET single-cell Li-Ion battery charger from TI.
