Charge parameters — current and safety timer — are set through the I²C interface rather than external resistors, which saves board area and allows dynamic adjustment by the system host. The device integrates over-voltage and over-temperature fault protection, a requirement for safe single-cell charging in portable equipment. ## Charge current ceiling and thermal budget At the 1.25 A maximum charge current, the linear regulator dissipates the voltage drop between the 6 V max supply and the battery voltage as heat. In a 20-DSBGA package with no exposed thermal pad, the PCB copper area under the device sets the effective thermal resistance — layout is not optional. ## 20-DSBGA package — what it means for assembly and rework The 20-DSBGA (0.4 mm pitch wafer-level package) requires a solder stencil designed for the small aperture size and a reflow profile that matches the JEDEC MSL level. The package is moisture-sensitive; a bake before rework is standard practice if the floor life has been exceeded.","metaTitle":"BQ24153YFFR single-cell Li-ion charger, 1.25 A max, I²C","metaDescription":"Texas Instruments BQ24153YFFR single-cell Li-Ion/Polymer charger with I²C interface. 1.25 A max charge current, over-voltage/over-temp protection.","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":"I²C","Mounting Type":"Surface Mount","Package / Case":"20-UFBGA, DSBGA","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24153","Battery Pack Voltage":"4.44V (Max)","Charge Current - Max":"1.25A","Operating Temperature":"-30°C~85°C(TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"6V","Supplier Device Package":"20-DSBGA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.4350","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/47fcc522ead5451199f4af6e2b8ec2dd.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does BQ24153YFFR have overvoltage protection?","answer":"Yes, the BQ24153YFFR includes both over-voltage and over-temperature fault protection as built-in safety features for single-cell Li-ion charging."},{"question":"What is the maximum charge current of BQ24153YFFR?","answer":"The maximum programmable charge current is 1.25 A, set via the I²C interface.
