For a typical 2000 mAh pack, that works out to a 0.5C charge rate — expect roughly two hours from empty to full, assuming the input supply can deliver the 1A plus overhead. Charge current and the safety timer are set with external resistors, not through a serial bus — no I2C or firmware involvement needed. This keeps the BOM simple and the charger block independent of the main MCU. ## Thermal budget in the 3x3 VSON At 1A charge current with a 4.2V battery and a 5V input, the linear regulator drops 0.8V, dissipating roughly 0.8W. The 10-VSON (3x3) exposed-pad package needs a solid thermal connection to a copper plane — the datasheet recommends multiple vias under the pad to the ground layer. Without that, the junction temperature climbs above the 85°C industrial limit. This part is safe to commit to a BOM for a production run without worrying about a near-term last-time-buy window. The device is ROHS3 compliant, which matches current assembly requirements for lead-free reflow.","metaTitle":"BQ24081DRCT – TI Li-Ion Charger, 1A, 10-VSON, Active","metaDescription":"Texas Instruments BQ24081DRCT single-cell Li-Ion/Polymer charger, 1A max charge current, programmable current & timer, -40°C to 85°C, 10-VSON (3x3) package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"10-VFDFN Exposed Pad","Product Status":"Active","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":"$2.1600","priceTiers":[{"qty":1,"price":"$2.16000","currency":"USD"},{"qty":10,"price":"$1.94400","currency":"USD"},{"qty":25,"price":"$1.83360","currency":"USD"},{"qty":100,"price":"$1.56240","currency":"USD"},{"qty":250,"price":"$1.46704","currency":"USD"},{"qty":500,"price":"$1.28366","currency":"USD"},{"qty":1250,"price":"$1.06360","currency":"USD"},{"qty":2500,"price":"$1.03800","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/998c4bd5d70ce127d3b5050f026b4b41.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24081DRCT/alternatives.json"},"ai":{"faq":[{"question":"How do I get current pricing and availability for BQ24081DRCT?","answer":"Submit an RFQ with your target quantity and required delivery window."},{"question":"What is the difference between BQ24081DRCT and BQ24080?","answer":"The BQ24081 includes a programmable safety timer that the BQ24080 lacks. Both are single-cell linear chargers with 1A max charge current and the same 10-VSON package, but the BQ24080 relies on the input current limit alone for protection, while the BQ24081 adds a timer that terminates charging if the cell does not reach the regulation voltage within the set period."},{"question":"How do I set the charge current for BQ24081DRCT?","answer":"Connect a resistor from the ISET pin to ground. The charge current is proportional to the current sourced from ISET: I_CHARGE = K_ISET × V_ISET / R_ISET, where K_ISET is typically 1000. For 1A, use a 1.0 kΩ resistor to ground. The datasheet provides a table of standard resistor values for common charge currents."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24081DRCT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24081DRCT when reusing this data.
