Charge current is constant and programmable up to 250 mA max, set by a single external resistor from the ISET pin to ground. The 6-DSBGA package measures roughly 0.9 mm x 1.4 mm — the smallest footprint in TI's BQ25101 family. ## Fault protection and temperature range On-chip fault protection covers over-temperature, over-voltage, and short-circuit conditions. The over-temperature shutdown protects the die during high-ambient or high-charge-current operation — relevant because the 6-DSBGA package has limited thermal mass. The 0°C lower limit means the charger does not support charging below freezing without an external temperature-sense circuit — a common requirement for Li-ion cells. For designs that need cold-charging, a part with a wider temp range or external NTC input would be needed. The base product number is BQ25101. ## Sourcing and package availability Surface-mount assembly on standard FR-4 with a 4-layer board recommended for thermal spreading under the DSBGA. Maximum supply voltage is 6.45 V. The charger regulates the battery voltage to 4.35 V — compatible with 4.35 V Li-ion cells, not the more common 4.2 V cells. If your BOM specifies a 4.2 V termination voltage, this part will overcharge the cell; verify the battery spec before committing.","metaTitle":"BQ25101HYFPR Texas Instruments Li-Ion Charger IC 250mA","metaDescription":"BQ25101HYFPR 1-cell Li-Ion/Polymer linear charger IC. 250 mA max charge current, programmable via external resistor.","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":"-","Mounting Type":"Surface Mount","Package / Case":"6-XFBGA, DSBGA","Product Status":"Active","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":"BQ25101","Battery Pack Voltage":"4.35V","Charge Current - Max":"250mA","Operating Temperature":"0°C~125°C(TJ)","Programmable Features":"Current","Voltage - Supply (Max)":"6.45V","Supplier Device Package":"6-DSBGA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8500","priceTiers":[{"qty":1,"price":"$1.85000","currency":"USD"},{"qty":10,"price":"$1.66000","currency":"USD"},{"qty":25,"price":"$1.56640","currency":"USD"},{"qty":100,"price":"$1.33460","currency":"USD"},{"qty":250,"price":"$1.25316","currency":"USD"},{"qty":500,"price":"$1.09650","currency":"USD"},{"qty":1000,"price":"$0.90854","currency":"USD"},{"qty":3000,"price":"$0.88667","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a481992022d76cb3311a91a612958d38.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25101HYFPR/alternatives.json"},"ai":{"faq":[{"question":"Is BQ25101HYFPR compatible with 4.2V batteries?","answer":"No. The battery regulation voltage is 4.35 V.
