The I²C interface lets a host controller set the charge current and timer limits. It lives in a 24-WFQFN exposed-pad package (4x4 mm body), which means the thermal pad under the IC is the primary heat path. On a 2-layer board the pad needs a via array to the ground plane; on a 4-layer board the inner planes pull heat away fast enough to sustain the 3.2 A charge rate at 85°C ambient. ## Key ratings that drive the BOM decision The battery pack voltage range is 4.6 V to 5.15 V. The regulation loop clamps at the programmed target. Supply voltage max is 13.5 V, so a 5 V USB input or a 9 V wall wart is fine; a 12 V rail is within spec but leaves only 1.5 V headroom above the 5.15 V pack ceiling — the linear regulator stage will dissipate the difference as heat, so the thermal budget needs checking at high charge current. Fault protection covers over-current, over-temperature, and over-voltage — the chip shuts itself down before the cell sees a runaway charge. The timer is programmable via I²C. The base product number BQ25611 covers the family; the DRTWR suffix identifies the 24-WQFN package and reel orientation. Sourced per RFQ — no stock-holding claim, but the active status means lead times are typically short through distribution.","metaTitle":"BQ25611DRTWR – TI 1-Cell Li-Ion Charger, 3.2 A, I²C, 24-WQFN","metaDescription":"Texas Instruments BQ25611DRTWR single-cell Li-Ion/Polymer charger. 3.2 A max charge current, I²C interface, industrial temp range, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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-WFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ25611","Battery Pack Voltage":"4.6V ~ 5.15V","Charge Current - Max":"3.2A","Operating Temperature":"-40°C ~ 85°C (TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"13.5V","Supplier Device Package":"24-WQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.7200","priceTiers":[{"qty":1,"price":"$3.72000","currency":"USD"},{"qty":10,"price":"$3.34100","currency":"USD"},{"qty":25,"price":"$3.15880","currency":"USD"},{"qty":100,"price":"$2.73760","currency":"USD"},{"qty":250,"price":"$2.59720","currency":"USD"},{"qty":500,"price":"$2.33048","currency":"USD"},{"qty":1000,"price":"$1.96546","currency":"USD"},{"qty":3000,"price":"$1.43733","currency":"USD"},{"qty":6000,"price":"$1.38330","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/91648935d076901ecb2021159e16aed5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25611DRTWR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the BQ25611DRTWR?","answer":"Within the same TI family, the BQ25616 is a common cross-shop candidate.
