The part integrates over-current and over-temperature fault protection, reducing the external component count for a compact charging solution. This is the IC you spec when you need a host-controlled fast charger for a single-cell portable — think power banks, handheld instruments, or any USB-C PD device that wants to charge a 1S pack quickly without a separate power-management MCU. It is ROHS3 compliant. For a new design, this is a safe choice — no LTB risk in the near term. There is no official second-source alternate in the ledger, but the I²C-controlled single-cell charger space has several functional competitors if dual-sourcing becomes a priority.","metaTitle":"TI BQ25892RTWT MaxCharge Li-Ion Charger IC, 5A, I²C, 24-WQFN","metaDescription":"Texas Instruments BQ25892RTWT single-cell Li-Ion/Polymer battery charger from the MaxCharge series.","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":"$4.8900","priceTiers":[{"qty":1,"price":"$4.89000","currency":"USD"},{"qty":10,"price":"$4.39000","currency":"USD"},{"qty":25,"price":"$4.15000","currency":"USD"},{"qty":100,"price":"$3.59660","currency":"USD"},{"qty":250,"price":"$3.41216","currency":"USD"},{"qty":500,"price":"$3.06170","currency":"USD"},{"qty":1250,"price":"$2.61000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/609b26e14eb86b27c75160b2e83a615e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25892RTWT/alternatives.json"},"ai":{"faq":[{"question":"Does BQ25892RTWT support I2C communication?","answer":"Yes, the BQ25892RTWT uses an I²C interface for host control, along with USB input detection.

BQ25892RTWT is supplied in Tape & Reel (TR) and Cut Tape (CT) options, while the BQ25892RTWR variant uses a different reel format. The silicon and electrical specifications are identical.
