Its 3.3V to 9V input range covers USB (5V) and regulated wall-adapter supplies, and the 1.1A supply current ceiling supports fast charging of 1000–2000 mAh cells without pushing the thermal budget of the 10-WSON package. ## 1.1A charge current — thermal reality check At 1.1A charge current, the power dissipation in the linear pass element is (VIN – VBAT) × ICHG. With a 5V input and a 3.7V battery, that is roughly 1.43 W. Layout is not optional; the thermal pad is the primary heat path. ## Active production — no allocation signal For new designs, this means standard franchise-channel availability with no near-term supply risk.","metaTitle":"BQ25046DQCT Texas Instruments Battery Charger IC","metaDescription":"BQ25046DQCT from TI — single-cell Li-ion charger IC, 3.3V to 9V input range, 1.1A supply current, 10-WSON package.","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)","Applications":"Handheld/Mobile Devices","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Supply":"1.1A","Voltage - Supply":"3.3V ~ 9V","Base Product Number":"BQ25046","Operating Temperature":"-40°C~85°C","Supplier Device Package":"10-WSON (3x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.3361","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a47451b030a9acbe8bdab313a9267dd0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the output current of BQ25046DQCT?","answer":"The supply current rating is 1.1A.
