Pack voltage tops at 18.048V, which covers a fully charged 4S Li-ion string at 16.8V with margin, or a 3S LiFePO4 stack at 10.8V nominal. The 24V maximum supply input gives headroom for a 19–20 V adapter rail; the IC drops the input to the programmed pack voltage through an integrated buck converter topology. ## Fault coverage and chemistry flexibility Built-in over-current and over-voltage protection means the IC can shut down the charge cycle without relying on the host microcontroller to monitor the rail — useful for standalone charger designs or as a safety monitor in a supervised system. Multi-chemistry support (Li-ion, LiFePO4, NiMH, lead-acid) is handled by the programmable charge voltage and current registers; the same BOM can serve different battery types by changing firmware constants.","metaTitle":"TI BQ24750ARHDR Battery Charger IC, 10A, 2-4 Cells, 28-VQFN","metaDescription":"Texas Instruments BQ24750ARHDR active multi-chemistry battery charger. 10A max charge current, 2-4 cells, 18.048V pack voltage max. 28-VQFN package.","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":"-","Mounting Type":"Surface Mount","Package / Case":"28-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"2 ~ 4","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Voltage","Battery Chemistry":"Multi-Chemistry","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24750","Battery Pack Voltage":"18.048V (Max)","Charge Current - Max":"10A","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"-","Voltage - Supply (Max)":"24V","Supplier Device Package":"28-VQFN (5x5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.4525","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/162cbe6356ebb9b21a640cd3f094f5f1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24750ARHDR/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum charge current and battery pack voltage for BQ24750ARHDR?","answer":"The IC supports a programmable constant charge current up to 10A and a maximum battery pack voltage of 18.048V, suitable for 2 to 4 series cells."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24750ARHDR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24750ARHDR when reusing this data.
