That current density means the thermal pad layout and PCB copper area directly set the sustained charge rate — the part can deliver the full 3A only when the board pulls heat away through the pad vias and internal plane. Input supply range goes to 13.5V max, covering USB BC1.2, standard 5V adapters, and 12V auxiliary rails without a front-end buck. The I2C interface lets the host set charge current and regulation voltage, so the same BOM works across different cell capacities by changing a few register writes. ## Protection set and battery chemistry match On-die fault protection covers over-current, over-temperature, over-voltage, and short-circuit events — no external comparator or supervisor needed for the basic safety envelope. The chemistry target is 1-cell Lithium Ion/Polymer with a maximum battery regulation voltage of 4.62V, suitable for the common 4.2V and 4.35V cell types. The programmable features are limited to charge current and voltage — no NTC thermistor input or JEITA profile on this variant, so external temperature monitoring falls to the host MCU through the I2C bus.","metaTitle":"BQ25601DRTWR I2C 1S Li-Ion Charger, 3A, 13.5V Input","metaDescription":"Texas Instruments BQ25601DRTWR 1-cell Li-Ion/Polymer charger with I2C control, 3A max charge current, 13.5V input, 24-WFQFN.","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-WFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature, Over Voltage, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ25601","Battery Pack Voltage":"4.62V (Max)","Charge Current - Max":"3A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current, Voltage","Voltage - Supply (Max)":"13.5V","Supplier Device Package":"24-WQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.6800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/998650e9fe203e25c182afff28023065.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between BQ25601 and BQ25601DRTWR?","answer":"BQ25601 is the base product number for the charger IC family.
