The I²C interface lets the host controller set the charge current, termination threshold, and safety timer without external resistors — useful when the same board must handle different battery capacities across product variants. The 24-VFQFN with exposed pad needs a thermal via array under the paddle to keep the junction below the thermal shutdown threshold during a 2.5 A charge cycle. ## Protection and package for production Texas Instruments continues to support this order code for new designs and ongoing production. On-chip fault protection includes over-temperature and over-voltage, which shuts down the pass FET before the die exceeds its safe operating area or the battery sees an overvoltage condition. The I²C bus also allows the host to read fault flags, so the system firmware can log a charge abort instead of just browning out. ## What the 2.5 A rating means for your BOM At 2.5 A, the linear pass element dissipates (Vin - Vbatt) × 2.5 A as heat. If your thermal budget is tight, consider a switching charger; if you need a simple, low-noise linear stage for a single-cell portable, this part keeps the BOM count low.","metaTitle":"BQ24161RGET Texas Instruments Li-Ion Charger IC – 2.5A, I²C","metaDescription":"Texas Instruments BQ24161RGET single-cell Li-Ion/Polymer charger IC.
