An I²C interface provides programmable charge current, termination threshold, and status monitoring — no external resistors for current setting, which saves board space but adds a firmware dependency. ## Industrial temperature grade and fault protection Fault protection includes over-voltage and short-circuit detection; the IC enters a safe state without latch-up, and the I²C bus reports the fault condition to the host controller. The 14 V maximum supply voltage gives headroom for a 5 V USB-C input or a 9 V wall adapter — the input over-voltage threshold is set internally, so no external OVP clamp is required for input rails below 14 V. ## Package — 36-DSBGA footprint and assembly Supplied in a 36-DSBGA package measuring 2.63 mm x 2.46 mm — the 0.4 mm ball pitch typical for this package requires a 4-layer or higher PCB with microvias for fan-out; two-layer boards will struggle to route all signals.","metaTitle":"BQ25910YFFT Texas Instruments Battery Charger IC – 6 A, I²C","metaDescription":"Texas Instruments BQ25910YFFT single-cell, multi-chemistry battery charger IC. 6 A max charge current, I²C interface, 4.775 V pack voltage, 36-DSBGA 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":"I²C","Mounting Type":"Surface Mount","Package / Case":"36-UFBGA, DSBGA","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Voltage, Short Circuit","Battery Chemistry":"Multi-Chemistry","Current - Charging":"Constant","Base Product Number":"BQ25910","Battery Pack Voltage":"4.775V","Charge Current - Max":"6A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"14V","Supplier Device Package":"36-DSBGA (2.63x2.46)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.8400","priceTiers":[{"qty":1,"price":"$6.84000","currency":"USD"},{"qty":10,"price":"$6.14600","currency":"USD"},{"qty":25,"price":"$5.81000","currency":"USD"},{"qty":100,"price":"$5.03520","currency":"USD"},{"qty":250,"price":"$4.77700","currency":"USD"},{"qty":500,"price":"$4.28638","currency":"USD"},{"qty":1250,"price":"$3.65400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d4c7f4b918fa394ed6f6a18a5ff89c69.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25910YFFT/alternatives.json"},"ai":{"faq":[{"question":"Is the BQ25910YFFT compatible with lithium polymer batteries?","answer":"Yes — the IC supports multi-chemistry single cells, and the 4.775 V pack voltage covers 4.2 V and 4.4 V Li-polymer termination voltages.
