The I²C interface lets you program charge current, voltage, and timer thresholds in firmware, eliminating resistor dividers for multi-chemistry or multi-application boards. ## Charge current and thermal budget The 1.5A max charge current is a practical ceiling for a single-cell Li-ion in the 25-DSBGA package. At 1.5A, the power dissipation in the pass element demands a solid copper pour on the PCB — the DSBGA's small footprint (roughly 3.5 mm × 3.5 mm) means the thermal path is through the solder balls and board vias, not a backside pad. Texas Instruments continues to manufacture and support the part — no last-time-buy deadline or obsolescence risk for current production runs. The ROHS3 compliance is current for global shipping.","metaTitle":"BQ24185YFFT Texas Instruments Li-Ion Charger IC – Active","metaDescription":"Texas Instruments BQ24185YFFT single-cell Li-Ion/Polymer charger IC. 1.5A max charge, 16V input, I²C interface, 25-DSBGA.
