The I²C interface lets the host controller program charge current and voltage thresholds on the fly — useful when the same PCB must support different battery chemistries or cell capacities across product variants. ## 300 mA charge current — sized for compact single-cell packs The maximum charge current is 300 mA. For a 200–500 mAh single-cell Li-ion or Li-Pol pack — common in wearable, hearable, and compact IoT sensor nodes — this current delivers a 1- to 3-hour charge cycle. The constant-current regulation profile, combined with the over-voltage and short-circuit fault protection, keeps the cell within its safe operating area without an external thermistor or protection IC in many designs. ## 25-DSBGA footprint — layout constraints for the small-package charger The supplier device package is 25-DSBGA. There is no last-time-buy notice to track and no successor part to qualify.","metaTitle":"Texas Instruments BQ25125YFPR Battery Charger IC, 20V Input","metaDescription":"Texas Instruments BQ25125YFPR single-cell multi-chemistry battery charger IC. 20V max input, 300 mA charge current, I²C programmable.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"25-XFBGA, 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":"BQ25125","Battery Pack Voltage":"5.5V (Max)","Charge Current - Max":"300mA","Operating Temperature":"-40°C~85°C(TJ)","Programmable Features":"Current, Voltage","Voltage - Supply (Max)":"20V","Supplier Device Package":"25-DSBGA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.1300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d7c8756f4c7b427b8c5f9f8bf7492718.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25125YFPR/alternatives.json"},"ai":{"faq":[{"question":"What are the operating conditions for BQ25125YFPR?","answer":"The supply voltage can go up to 20V.
