It integrates a USB-compatible input interface and delivers a programmable constant charge current up to 1 A, with built-in over-temperature and over-voltage fault protection. ## Charge current and thermal management at the exposed pad The charge current is programmable via an external resistor, allowing the designer to trade off charge time against thermal budget for the board layout. Maximum supply voltage is 10.2 V, so the input rail should be a regulated 5 V USB bus or a clean DC supply — not an unregulated wall adapter that can sag or spike.","metaTitle":"BQ25071DQCR LiFePO4 Battery Charger IC, 1A, 10-WSON","metaDescription":"Texas Instruments BQ25071DQCR is a 1-cell LiFePO4 linear charger with 1A max charge current, USB interface, and over-voltage protection.","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":"USB","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Lithium Iron Phosphate","Current - Charging":"Constant - Programmable","Base Product Number":"BQ25071","Battery Pack Voltage":"3.5V","Charge Current - Max":"1A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"10.2V","Supplier Device Package":"10-WSON (3x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8670","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/64ff155e47163c153aac6111a4271f3f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can BQ25071DQCR be used for 1-cell LiFePO4 batteries at 3.5 V?","answer":"Yes, the BQ25071DQCR is designed specifically for single-cell LiFePO4 chemistry with a regulated battery pack voltage of 3.5 V."},{"question":"What is the difference between BQ25071DQCR and BQ25070?","answer":"The BQ25071 is a 1-cell LiFePO4 charger at 3.5 V pack voltage, while the BQ25070 targets 1-cell Li-ion at 4.2 V — the chemistry and voltage setpoint are the primary difference."},{"question":"What is the lead time for ordering BQ25071DQCR from distributors?","answer":"Lead time is confirmed at quote time against the specific BOM quantity."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ25071DQCR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ25071DQCR when reusing this data.
