It integrates over-temperature, over-voltage, and short-circuit fault protection, reducing the external component count for a compact charging solution. ## Charge current and protection thresholds The charge current is programmable up to 250 mA maximum, and the battery regulation voltage is fixed at 4.2 V for single-cell Li-Po and Li-Ion cells. Fault protection is built in: over-temperature shutdown, over-voltage clamp, and short-circuit current limiting. ## Package and mounting Housed in a 6-bump DSBGA package on a 6-XFBGA substrate. The footprint suits wearable, hearable, and IoT end-nodes where PCB real estate is tight. Surface-mount assembly with a standard lead-free reflow profile. The maximum supply voltage is 6.45 V, allowing direct connection to a 5 V USB bus or a regulated 5 V rail without an external LDO.","metaTitle":"BQ25101YFPT Li-Ion Linear Charger, 250 mA max, 6-DSBGA","metaDescription":"Texas Instruments BQ25101YFPT single-cell Li-Ion/Polymer linear charger.","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":"4.2V","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 for BQ25101YFPT?","answer":"The maximum charge current is 250 mA, programmable via an external resistor.
