The 14V maximum supply voltage gives headroom for USB-C PD adapters or 12V barrel jacks without an external pre-regulator. Over-current and over-temperature protection are built in, so the charger can safely terminate a charge cycle if the cell gets hot or the load pulls too much. A 5A max charge current lets you size the charging path for fast turnaround. The I²C interface lets you dial back the current for smaller cells or thermal budgets. Texas Instruments continues to manufacture it, so there's no LTB or EOL pressure for new designs. The base product number is BQ25890 — the HRTWR suffix denotes the 24-WQFN package and tape-and-reel / cut-tape shipping options.","metaTitle":"BQ25890HRTWR Li-Ion Charger IC, 5A Max, I²C, 24-WQFN","metaDescription":"TI BQ25890HRTWR MaxCharge™ single-cell Li-Ion/Polymer charger with 5A max charge current, I²C/USB interface, over-current and over-temperature protection.","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, USB","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":"BQ25890","Battery Pack Voltage":"-","Charge Current - Max":"5A","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":"$4.0700","priceTiers":[{"qty":1,"price":"$4.07000","currency":"USD"},{"qty":10,"price":"$3.65800","currency":"USD"},{"qty":25,"price":"$3.45840","currency":"USD"},{"qty":100,"price":"$2.99720","currency":"USD"},{"qty":250,"price":"$2.84344","currency":"USD"},{"qty":500,"price":"$2.55142","currency":"USD"},{"qty":1000,"price":"$2.17500","currency":"USD"},{"qty":3000,"price":"$2.17500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e9f92e5270bad6fdc0a2f6a7626a3155.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25890HRTWR/alternatives.json"},"ai":{"faq":[{"question":"What is the charge current range and battery chemistry supported by BQ25890HRTWR?","answer":"It supports single-cell Lithium Ion/Polymer batteries with a maximum charge current of 5A.
