The part integrates fault protection for over-current and over-temperature conditions, which simplifies the BOM by reducing the need for external supervisory circuitry. ## Package and footprint — 24-WQFN with exposed pad It does not extend to the full automotive under-hood range (125°C), but it handles the cabin and most portable use cases without issue. The part is ROHS3 compliant.","metaTitle":"BQ25892RTWR TI MaxCharge Li-Ion Charger IC, 5A I²C/USB","metaDescription":"Texas Instruments BQ25892RTWR single-cell Li-Ion/Polymer charger IC, MaxCharge series. 5A max charge current, I²C/USB interface, -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, 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":"BQ25892","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/609b26e14eb86b27c75160b2e83a615e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25892RTWR/alternatives.json"},"ai":{"faq":[{"question":"Can BQ25892RTWR charge at 5 A continuously?","answer":"Yes, the 5 A maximum charge current is a continuous rating, not a peak.
