It delivers up to 1.5 A charge current to a single cell with a maximum battery pack voltage of 4.44 V, covering standard 4.2 V and 4.35 V termination voltages. Built-in fault protection includes over-temperature and over-voltage shutdown, reducing external component count for a compact charger design. The 1.5 A maximum charge current suits single-cell Li-ion packs in the 1000–3000 mAh range, delivering a 1C to 0.5C charge rate that balances charge time and cell longevity. The programmable current feature lets you adjust the rate via I²C to match the cell manufacturer's recommended charge profile. With a battery pack voltage ceiling of 4.44 V, this part supports both standard 4.2 V Li-ion cells and the higher-voltage 4.35 V Li-Po chemistries common in slim portable devices. The 9 V maximum supply input gives headroom for 5 V USB or 9 V wall adapters. ## Package and thermal considerations for the 30-DSBGA The 30-DSBGA package (30-UFBGA, DSBGA) is a fine-pitch BGA with 0.5 mm ball pitch, requiring a 4-layer PCB with thermal vias under the die pad to dissipate heat from the 1.5 A charge pass element. Surface-mount assembly with a standard lead-free reflow profile works, but the small BGA body demands precise solder paste volume and X-ray inspection for voiding under the thermal pad.","metaTitle":"BQ24140YFFR Texas Instruments Battery Charger IC, 1.5 A, I²C","metaDescription":"Texas Instruments BQ24140YFFR single-cell Li-ion/Li-Po charger IC with I²C control, max charge current 1.5 A, 4.44 V battery pack voltage, -30°C to 85°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); Cut Tape (CT)","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"30-UFBGA, DSBGA","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24140","Battery Pack Voltage":"4.44V (Max)","Charge Current - Max":"1.5A","Operating Temperature":"-30°C~85°C(TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"9V","Supplier Device Package":"30-DSBGA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3250","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/09bd9ce9034f245e93acd969bbf4474b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the BQ24140YFFR compatible with single-cell Li-Po batteries?","answer":"Yes, it supports single-cell Li-Po batteries with a maximum pack voltage of 4.44 V, covering both standard 4.2 V and 4.35 V termination chemistries."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24140YFFR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24140YFFR when reusing this data.
