It targets space-constrained portable designs where the 6-XFBGA/DSBGA package (1.5 mm × 1.5 mm typical) keeps the PCB footprint minimal. The charger operates from a supply up to 6.45 V and terminates at a battery regulation voltage of 4.35 V. ## 250 mA charge current — sizing the charge time The 250 mA maximum charge current sets the charge rate for a single-cell Li-Ion pack. For a 500 mAh cell, a full constant-current charge takes roughly two hours at this rate, assuming the power supply can deliver the input current without dropout. The current is programmable via an external resistor, so the BOM can tune the charge profile to the battery capacity. ## Fault protection and temperature range Built-in fault protection covers over-temperature, over-voltage, and short-circuit conditions — three safeguards that matter when the battery is in a sealed enclosure or subject to a fault on the input rail. ## Package and mounting The 6-DSBGA package is a 0.5 mm pitch wafer-level chip-scale package. Surface-mount assembly requires a solder stencil designed for the bump pattern and a reflow profile compatible with the package's moisture sensitivity level. The small body means the thermal pad area is limited — the PCB copper plane under the package acts as the primary heat sink during charging.","metaTitle":"BQ25101HYFPT Linear Charger IC, 250 mA, 6-DSBGA","metaDescription":"Texas Instruments BQ25101HYFPT single-cell Li-Ion/Polymer linear charger, 250 mA max charge current, 6-DSBGA package, 0°C to 125°C junction range.","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":"-","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":"$2.2100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2664c95aface018fc0447f7043f7e575.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current of BQ25101HYFPT?","answer":"The maximum charge current is 250 mA, programmable via an external resistor."},{"question":"Does BQ25101HYFPT have over-temperature protection?","answer":"Yes, the charger includes over-temperature, over-voltage, and short-circuit fault protection."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ25101HYFPT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ25101HYFPT when reusing this data.
