The part integrates over-temperature, over-voltage, and short-circuit protection — three fault monitors that cover the common failure modes in a portable charge path. The BQ25100HYFPT comes in a 6-ball DSBGA (6-XFBGA) package, 0.4 mm pitch, no leads exposed — it's a wafer-level chip-scale package. The pad layout is the same as the supplier device package 6-DSBGA. Surface-mount only; the small ball array means the PCB fan-out is straightforward on a two-layer board, but the 0.4 mm pitch demands a solder-paste stencil with 0.2 mm apertures and a reflow profile that stays below 260 °C peak. Under a hot-air station, the part lifts cleanly if the board is preheated to 100 °C — the low thermal mass of the DSBGA means it reflows fast, so watch the soak time to avoid cold joints on the outer balls.","metaTitle":"BQ25100HYFPT Li-Ion Linear Charger IC, 250 mA, 6-DSBGA","metaDescription":"Texas Instruments BQ25100HYFPT single-cell Li-Ion/Polymer linear charger IC. 250 mA max charge current, 4.35 V battery pack voltage, 6-DSBGA package.","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":"BQ25100","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 charge current of BQ25100HYFPT?","answer":"The maximum charge current is 250 mA, and it is programmable via an external resistor. The part is a constant-current / constant-voltage linear charger, so the actual charge current is set by the resistor value and limited by the 250 mA ceiling."},{"question":"Is BQ25100HYFPT compatible with 4.2 V batteries?","answer":"Yes, but with a caveat: the battery pack voltage is 4.35 V, meaning the charger terminates at 4.35 V. If you use a standard 4.2 V Li-ion cell, the charger will overcharge it to 4.35 V, which exceeds the cell's safe voltage. For 4.2 V cells, you need a charger with a 4.2 V termination threshold. This part is designed for 4.35 V cells."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ25100HYFPT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ25100HYFPT when reusing this data.
