The maximum supply voltage of 14 V allows the device to operate from standard USB adapters, 5 V wall chargers, and higher-voltage input sources such as 12 V regulated rails, provided the input stays within the absolute maximum rating. ## I²C programmability and fault protection An I²C serial interface (alongside USB detection logic) gives the host microcontroller control over charge current, termination threshold, input current limit, and timer settings — the charger is not a fixed-function part but a configurable power management IC. Built-in fault protection covers over-current and over-temperature conditions, shutting down the power stage before the die or external components exceed safe limits.","metaTitle":"BQ25890RTWR Texas Instruments Power Management IC, 5A","metaDescription":"Texas Instruments BQ25890RTWR MaxCharge™ single-cell Li-ion charger, 5A max charge current, I²C/USB interface, 14V supply max, -40°C to 85°C, 24-WQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":null},"links":{"datasheetUrl":"https://cdn.icboms.com/609b26e14eb86b27c75160b2e83a615e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25890RTWR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ25890RTWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ25890RTWR when reusing this data.
