Its headline rating is a maximum charge current of 1.5 A, which sets the charge time for a typical 3.7 V Li-Ion pack. For a 2000 mAh cell, that is roughly an 80-minute constant-current charge phase before the CV taper begins. The charge current is programmable via I²C, so the host microcontroller can adjust the rate based on input power availability, battery temperature, or system load. This is the feature that distinguishes it from a fixed-current charger — you can trade charge speed for thermal budget on the fly. ## Protection set and package thermal reality Fault protection covers over-temperature, over-voltage, and short circuit — the three failure modes that matter most for Li-Ion charging. The over-voltage protection clamps the battery voltage; the thermal shutdown prevents runaway if the 4x4 mm QFN pad cannot sink the heat from a sustained 1.5 A charge. The datasheet layout recommendation calls for at least nine vias in the pad area — a two-layer board with a solid ground plane works, but a four-layer stack gives better thermal spreading. ## Sourcing and lifecycle posture No official second-source or pin-compatible alternate is listed in the TI portfolio, so the BOM carries a single-source risk for this charger function.","metaTitle":"BQ24271RGET Li-Ion Charger IC, 1.5A, I²C, 24-VQFN","metaDescription":"Texas Instruments BQ24271RGET single-cell Li-Ion battery charger with I²C programmable current up to 1.5A.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage, Short Circuit","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24271","Battery Pack Voltage":"3.7V","Charge Current - Max":"1.5A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current","Voltage - Supply (Max)":"6V","Supplier Device Package":"24-VQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.0200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ba7aacc3fe60d4ba136ee427e966c031.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between the BQ24271RGET and the BQ24270?","answer":"The BQ24271 adds I²C programmability for the charge current, while the BQ24270 uses a fixed resistor to set the current.
