Maximum charge current is 1.5A, and the battery regulation voltage tops out at 4.52V — typical for a single-cell Li-Ion termination point. The 30-DSBGA package (0.5 mm pitch, wafer-level) keeps the footprint small, but the thermal dissipation path runs through the board — the 1.5A ceiling is where the package and the copper area meet. ## 1.5A charge current in a 30-DSBGA — thermal planning matters At 1.5A continuous charge, the internal FET dissipation depends on input-to-battery differential; a higher differential raises die temperature, and the DSBGA relies on the PCB copper for heat spreading. Fault protection covers over-current and over-voltage events, which helps when the input rail is noisy or the battery is disconnected mid-cycle. Supply voltage range extends to 13.5V max, so it can handle 5V USB or 9V/12V adapters without an external pre-regulator. ROHS3 compliant, surface-mount in a 30-DSBGA — the reel and cut-tape options let you order prototype quantities or production reels.","metaTitle":"BQ25618YFFR 1.5A I²C Li-Ion Charger","metaDescription":"Texas Instruments BQ25618YFFR single-cell Li-Ion battery charger with I²C interface, 1.5A max charge current, 4.52V battery voltage, industrial temp range.","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":"I²C","Mounting Type":"Surface Mount","Package / Case":"30-UFBGA, DSBGA","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ25618","Battery Pack Voltage":"4.52V (Max)","Charge Current - Max":"1.5A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current, Timer, Voltage","Voltage - Supply (Max)":"13.5V","Supplier Device Package":"30-DSBGA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.1300","priceTiers":[{"qty":1,"price":"$4.13000","currency":"USD"},{"qty":10,"price":"$3.70900","currency":"USD"},{"qty":25,"price":"$3.50600","currency":"USD"},{"qty":100,"price":"$3.03850","currency":"USD"},{"qty":250,"price":"$2.88268","currency":"USD"},{"qty":500,"price":"$2.58662","currency":"USD"},{"qty":1000,"price":"$2.20500","currency":"USD"},{"qty":3000,"price":"$2.20500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/045f9bdd54a19b57831bbbf71a44a051.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25618YFFR/alternatives.json"},"ai":{"faq":[{"question":"Does BQ25618YFFR support I²C?","answer":"Yes, the charge current, voltage, and timer are all programmable via an I²C interface."},{"question":"What is the charge current of BQ25618YFFR?","answer":"Maximum charge current is 1.5A, programmable via I²C."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ25618YFFR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ25618YFFR when reusing this data.
