At 3 A the die temperature climbs fast; the datasheet's thermal pad layout recommendation needs to be followed to keep the charger from throttling back on a hot bench. ## I²C control — programmable current and fault monitoring The I²C interface lets the host microcontroller set the charge current on the fly and read fault conditions. Over-temperature and over-voltage protection are built in — the charger shuts down before the silicon or the battery sees an excursion. That makes this part a fit for designs where the system processor manages the charging profile rather than relying on a fixed resistor divider. ## Industrial temperature grade — outdoor and enclosure use The 13.2 V max supply input gives headroom for 5 V USB or 12 V wall-adapter rails without an external pre-regulator.","metaTitle":"BQ24261MRGET Li-Ion Charger IC, 3A, I²C, 24-VQFN, Obsolete","metaDescription":"Texas Instruments BQ24261MRGET single-cell Li-Ion battery charger with I²C interface, 3A max charge current, -40°C to 85°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Obsolete","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24261","Battery Pack Voltage":"3.5V","Charge Current - Max":"3A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current","Voltage - Supply (Max)":"13.2V","Supplier Device Package":"24-VQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$101.9300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fb270a2c480daf4c50857a7835554454.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BQ24261MRGET?","answer":"No official replacement or cross-reference is listed by Texas Instruments for the BQ24261MRGET.
