This wide input range lets it draw from a regulated 5V bus, a 12V supply, or an unregulated 24V industrial rail without a pre-regulator. ## 16-VQFN (3.5x3.5) – small footprint with thermal pad Housed in a 16-VQFN (3.5x3.5) package with an exposed pad, the BQ24640RVAR fits tight PCB layouts common in portable or embedded supercapacitor modules. The IC draws a supply current of 1mA, a low overhead that matters in always-on or low-power standby systems where every milliamp counts. ## Active lifecycle – no obsolescence watch needed The part is ROHS3 Compliant, covering the latest EU restriction requirements — no exemption expiry concern for new designs.","metaTitle":"BQ24640RVAR Supercapacitor Charger IC – Texas Instruments","metaDescription":"BQ24640RVAR from TI: synchronous switch-mode supercapacitor charger, 5V–28V input, 1mA supply current, -40°C to 85°C, 16-VQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Applications":"Supercapacitor Charger","Mounting Type":"Surface Mount","Package / Case":"16-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Supply":"1mA","Voltage - Supply":"5V ~ 28V","Base Product Number":"BQ24640","Operating Temperature":"-40°C~85°C","Supplier Device Package":"16-VQFN (3.5x3.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.1900","priceTiers":[{"qty":1,"price":"$5.19000","currency":"USD"},{"qty":10,"price":"$4.66200","currency":"USD"},{"qty":25,"price":"$4.40760","currency":"USD"},{"qty":100,"price":"$3.81980","currency":"USD"},{"qty":250,"price":"$3.62392","currency":"USD"},{"qty":500,"price":"$3.25174","currency":"USD"},{"qty":1000,"price":"$2.77200","currency":"USD"},{"qty":3000,"price":"$2.77200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4976c0d7630a56058c22db892ec4dedd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24640RVAR/alternatives.json"},"ai":{"faq":[{"question":"Does BQ24640RVAR work for charging supercapacitors?","answer":"Yes, the BQ24640RVAR is specifically designed as a supercapacitor charger.
