The 30-DSBGA package (0.4 mm pitch typical for this family) demands careful PCB layout: a solid thermal via pattern under the package is needed to pull heat away from the die during a full 1.5 A charge cycle. The land pattern follows the standard DSBGA footprint; stencil aperture design for the solder balls is critical to avoid head-in-pillow defects in reflow. ## Programming charge parameters over I²C The I²C bus is the only control interface — no standalone pin-strap resistors for current setting. The host writes to registers to set the charge current (programmable up to 1.5 A), charge timer, and target battery voltage (max 4.52 V). This makes the BQ25618YFFT a good fit for designs where the system microcontroller already manages the PMIC bus and can adjust the charge profile in firmware for different battery chemistries or capacities. The overcurrent and overvoltage fault protection are hardware-enforced, independent of the I²C communication state.","metaTitle":"BQ25618YFFT battery charger IC, 1.5 A max, I²C, 30-DSBGA","metaDescription":"Texas Instruments BQ25618YFFT single-cell Li-ion charger, 1.5 A max, I²C programmable, -40°C to 85°C, active production.","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":"$4.9600","priceTiers":[{"qty":1,"price":"$4.96000","currency":"USD"},{"qty":10,"price":"$4.45000","currency":"USD"},{"qty":25,"price":"$4.20720","currency":"USD"},{"qty":100,"price":"$3.64620","currency":"USD"},{"qty":250,"price":"$3.45920","currency":"USD"},{"qty":500,"price":"$3.10394","currency":"USD"},{"qty":1250,"price":"$2.64600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/045f9bdd54a19b57831bbbf71a44a051.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25618YFFT/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum charge current for BQ25618YFFT?","answer":"The maximum programmable charge current is 1.5 A.
