It integrates pass transistor, current sensing, and thermal regulation in a 6-bump DSBGA package that measures roughly 0.9 mm × 0.9 mm — small enough for a wearable earbud or a medical patch. ## Charge termination and protection The charger terminates at a battery pack voltage of 4.284 V, matching the standard Li-ion 4.2 V cell with a small overcharge margin. Fault protection covers over-temperature, over-voltage, and short-circuit conditions — the chip shuts down before the cell or the board trace sees damage. The USB interface simplifies connection to a standard 5 V USB port or a regulated wall adapter; the input supply maximum is 6.45 V, so a 5 V rail leaves enough headroom for the linear regulator dropout without risking overvoltage. For a BOM that expects to run for another 18–24 months, this part does not force a respin.","metaTitle":"BQ25100BYFPR Linear Li-Ion Charger IC, 250 mA Max, 6-DSBGA","metaDescription":"BQ25100BYFPR is a single-cell Li-ion/Polymer linear charger IC with 250 mA max charge current, USB interface, and over-temperature/voltage/short-circuit","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":"USB","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":"BQ25100","Battery Pack Voltage":"4.284V","Charge Current - Max":"250mA","Operating Temperature":"-5°C~125°C(TJ)","Programmable Features":"Current","Voltage - Supply (Max)":"6.45V","Supplier Device Package":"6-DSBGA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8820","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9e4b43930ef821eecb194f6561ec6cfb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current for BQ25100BYFPR?","answer":"The maximum charge current is 250 mA, programmable via an external resistor."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ25100BYFPR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ25100BYFPR when reusing this data.
