The maximum charge current is 4 A, which defines the inductor and sense-resistor sizing on the power stage. The I²C bus also gives the system access to charge status, fault flags, and termination voltage configuration — the firmware engineer needs to budget a few hundred bytes of code for the initialization sequence and fault polling. ## 100-VQFN-MR — thermal pad is part of the circuit Surface-mount assembly with the exposed pad means the reflow profile must include a soak zone long enough to wet the pad fully — a standard JEDEC profile for a 9x9 mm QFN works, but the inner-row pads reduce the clearance for fan-out traces on a two-layer board. Maximum supply voltage is 17 V, which covers typical 2- and 3-cell Li-ion stacks (8.4 V and 12.6 V nominal) plus headroom for the input adapter. ## Sourcing and quoting for the BOM line The active lifecycle means there is no urgency to stockpile; standard procurement cycles apply.","metaTitle":"TPS65090ARVNT Battery Charger IC, 4A I²C, 2-3 Cell Li-ion","metaDescription":"Texas Instruments TPS65090ARVNT power management IC with I²C interface, programmable 4A charge current for 2-3 cell Li-ion/Polymer packs.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"100-VQFN Dual Rows, Exposed Pad","Product Status":"Active","Number of Cells":"2 ~ 3","lifecycle_stage":"eol_hot","Fault Protection":"-","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"TPS65090","Battery Pack Voltage":"-","Charge Current - Max":"4A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"17V","Supplier Device Package":"100-VQFN-MR (9x9)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.7354","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/abca77f328a68cc599c5dbcdbbef3e3e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65090ARVNT/alternatives.json"},"ai":{"faq":[{"question":"Can TPS65090ARVNT charge 4S Li-ion batteries?","answer":"No. The device is specified for 2 to 3 series cells. A 4S pack (16.8 V nominal) exceeds the 17 V maximum supply rating with no margin for the charger's own dropout, and the cell-count logic does not support four cells."},{"question":"What is the closest pin-compatible alternative to TPS65090ARVNT in this component family?","answer":"The base product number is TPS65090. The TPS65090ARVNR is the same die in a different reel/tape variant — the suffix difference (RVT vs RVN) relates to packaging and reel quantity, not pinout or electrical specification. Confirm the specific suffix against your BOM's packing requirement before substituting."},{"question":"How to configure charging current via I2C on TPS65090ARVNT?","answer":"The charge current is set through the I²C interface by writing to the charge-current register. The range is programmable from a low trickle up to the 4 A maximum. The host must initialize the I²C registers after power-up before charging begins — the default state is typically charge disabled."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS65090ARVNT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS65090ARVNT when reusing this data.
