The I²C interface lets the system host set charge current, termination threshold, and safety timers without external resistor dividers — useful when the same PCB must support different cell capacities. ## Charge current, input voltage, and thermal budget The 3A max charge current is the thermal design target for the 24-WQFN (4x4 mm) package with exposed pad. Input voltage tolerance to 14V covers common USB-C PD profiles and legacy 12V wall adapters, but the actual charge voltage for a single Li-ion cell stays at the standard 4.2V or 4.35V termination programmed via I²C. Fault protection includes over-current and over-temperature shutdown, which prevents runaway if the cell or adapter is shorted. ## Active production — no end-of-life concerns ROHS3 compliant, so it passes EU and global environmental requirements without exemption paperwork. ## Package and footprint — 24-WFQFN with exposed pad Supplied in a 24-WFQFN exposed pad package (4x4 mm, 0.50 mm pitch). The supplier device package is 24-WQFN (4x4).","metaTitle":"BQ25896RTWR — TI MaxCharge Li-Ion Battery Charger IC, 1-Cell","metaDescription":"Texas Instruments BQ25896RTWR MaxCharge single-cell Li-ion charger, 3A max charge current, I²C control, 14V input, -40°C to 85°C, 24-WQFN.","metaKeywords":null},"attributes":{"series":"MaxCharge™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"MaxCharge™","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","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"-","Base Product Number":"BQ25896","Battery Pack Voltage":"-","Charge Current - Max":"3A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"14V","Supplier Device Package":"24-WQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5500","priceTiers":[{"qty":1,"price":"$4.55000","currency":"USD"},{"qty":10,"price":"$4.08700","currency":"USD"},{"qty":25,"price":"$3.86360","currency":"USD"},{"qty":100,"price":"$3.34850","currency":"USD"},{"qty":250,"price":"$3.17680","currency":"USD"},{"qty":500,"price":"$2.85056","currency":"USD"},{"qty":1000,"price":"$2.43000","currency":"USD"},{"qty":3000,"price":"$2.43000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ec49bf31925d21f5eace870b996b9d71.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25896RTWR/alternatives.json"},"ai":{"faq":[{"question":"Does BQ25896RTWR support I²C programming?","answer":"Yes, the charge current, termination voltage, safety timer, and other parameters are set through the I²C interface.
