It communicates over an I²C interface, letting firmware set the charge current and monitor status without external resistors. ## NRND — plan your BOM transition That means TI is not actively promoting it for new projects, though existing production may continue for a time. ## Package and mounting The 300 mA ceiling suits wearable and IoT devices with small-capacity cells (100–500 mAh range). The I²C interface lets you adjust charge current on the fly, which is handy for thermal management in compact enclosures. ## Fault protection and package reality On-chip protection covers over-temperature, over-voltage, and short-circuit conditions — no external supervisory IC needed. The 25-DSBGA package measures roughly 2.1 mm × 2.1 mm, which saves board area but demands a controlled solder profile and X-ray inspection post-reflow. Cut Tape or Tape & Reel options are available for prototyping or production.","metaTitle":"BQ25120YFPT Battery Charger IC, 300 mA, I²C, 25-DSBGA","metaDescription":"Texas Instruments BQ25120YFPT single-cell Li-Ion/Polymer charger IC with 300 mA max charge current, I²C interface, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","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":"25-XFBGA, DSBGA","Product Status":"Not For New Designs","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ25120","Battery Pack Voltage":"4.2V","Charge Current - Max":"300mA","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"Current","Voltage - Supply (Max)":"5.5V","Supplier Device Package":"25-DSBGA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.3700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3681d9549b5d911afd0df281bfda88f3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ25120YFPT obsolete or NRND?","answer":"It is not fully discontinued, but TI recommends moving to a current-generation equivalent for new projects."},{"question":"What is the maximum charge current of BQ25120YFPT?","answer":"The maximum charge current is 300 mA, programmable via the I²C interface."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ25120YFPT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ25120YFPT when reusing this data.
