It delivers a regulated 4.2V charge voltage and supports a programmable charge current up to 1A. The device is built for constant-current / constant-voltage (CC/CV) charging with programmable current and timer settings, giving the designer control over the charge profile without external passives. Housed in a 10-pin VSON package with an exposed thermal pad (3×3 mm), it suits space-constrained portable designs where thermal dissipation from the linear regulator matters. The 4.2V battery voltage is the standard termination voltage for most single-cell Li-ion and Li-Po cells. The 1A maximum charge current sets the thermal ceiling — in a linear charger, the power dissipated as heat equals (VIN - VBAT) × ICHG, so a 5V input at 1A into a 3.7V cell dissipates 1.3W. The programmable timer prevents overcharging if the termination current threshold is never reached — a safety net for cells with high internal impedance or when the input supply is marginal. The linear topology means the die temperature tracks the ambient plus the self-heating from the charge current.","metaTitle":"BQ24081DRCRG4 Li-Ion Charger IC, 1A, 4.2V, 10-VSON","metaDescription":"Texas Instruments BQ24081DRCRG4 single-cell Li-Ion/Polymer charger IC.","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":"10-VFDFN Exposed Pad","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"-","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24081","Battery Pack Voltage":"4.2V","Charge Current - Max":"1A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"6.5V","Supplier Device Package":"10-VSON (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$58.8000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/998c4bd5d70ce127d3b5050f026b4b41.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ24081DRCRG4 compatible with 4.2V Li-ion batteries?","answer":"Yes, the BQ24081DRCRG4 is designed for single-cell Lithium Ion and Lithium Polymer batteries with a 4.2V charge voltage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24081DRCRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24081DRCRG4 when reusing this data.
