This reduces BOM line count when a product ships with multiple battery options. Programmable features include a Timer and Voltage threshold — the charge termination is set by external components, not fixed internally, so the same PCB layout serves different cell counts and chemistries by changing a few passives. Supply voltage max is 6V, which limits the input rail to a single-cell Li-ion (4.2V full charge) or a 5V USB bus. For higher-voltage packs (e.g., 12V lead-acid), an external step-down regulator is needed ahead of this IC. ## Temperature grade and package — commercial ambient, small footprint Operating temperature range is -20°C to 70°C, covering commercial and most industrial ambient environments but not automotive under-hood or extended outdoor exposure. The 8-TSSOP package with 0.65mm pitch fits into compact charger designs where board space is tight. Surface-mount assembly with Tape & Reel packaging — standard for volume pick-and-place. The 8-TSSOP body is 3.0mm × 4.4mm, so the decoupling cap and resistor divider fit within a 10mm × 10mm layout area.","metaTitle":"BQ24400PWR Texas Instruments Battery Charger IC, 8-TSSOP","metaDescription":"BQ24400PWR from Texas Instruments — active-production multi-chemistry battery charge controller. 6V max supply, programmable timer/voltage, -20°C to 70°C.","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)","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Number of Cells":"-","lifecycle_stage":"eol_hot","Fault Protection":"-","Battery Chemistry":"Multi-Chemistry","Current - Charging":"-","Base Product Number":"BQ24400","Battery Pack Voltage":"-","Charge Current - Max":"-","Operating Temperature":"-20°C~70°C(TA)","Programmable Features":"Timer, Voltage","Voltage - Supply (Max)":"6V","Supplier Device Package":"8-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.4435","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/981d3c500f4cf618ecc3dfc38bb8df53.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24400PWR/alternatives.json"},"ai":{"faq":[{"question":"What battery chemistries does the BQ24400PWR support?","answer":"The BQ24400PWR supports Multi-Chemistry batteries, including lead-acid, Li-ion, and NiMH.
