It manages the charge cycle for sealed and flooded lead-acid chemistries, handling a maximum supply voltage of 40 V. The surface-mount SOIC-16 footprint (0.295\" body width, 7.50 mm) is standard for medium-power analog ICs. ## 40 V supply ceiling and thermal envelope The 40 V maximum supply voltage means the BQ24450DW can regulate charge from a 24 V AC adapter or a solar panel string that reaches 36 V open-circuit — the internal series-pass element and control logic survive the full rail without an external pre-regulator. At the 70°C upper limit the die temperature stays within the silicon rating as long as the SOIC-16's thermal pad (if present) sees a copper plane on the PCB. No stock-holding claim is made; the part is quoted per the BOM quantity.","metaTitle":"Texas Instruments BQ24450DW Lead-Acid Charge Controller, 40V","metaDescription":"Texas Instruments BQ24450DW lead-acid battery charge controller IC. 40V max supply, -40°C to 70°C range, 16-SOIC.","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":"Tube","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","Product Status":"Active","Number of Cells":"-","lifecycle_stage":"eol_hot","Fault Protection":"-","Battery Chemistry":"Lead Acid","Current - Charging":"-","Base Product Number":"BQ24450","Battery Pack Voltage":"-","Charge Current - Max":"-","Operating Temperature":"-40°C~70°C(TJ)","Programmable Features":"-","Voltage - Supply (Max)":"40V","Supplier Device Package":"16-SOIC"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$13.6700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/485cfae0ff44908e032efa97ed525343.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24450DW/alternatives.json"},"ai":{"faq":[{"question":"What package does BQ24450DW come in?","answer":"It ships in Tube packaging."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24450DW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24450DW when reusing this data.
