It delivers up to 1.25 A of programmable charge current to a single cell with a maximum battery pack voltage of 4.44 V. ## 1.25 A charge current and 4.44 V ceiling The maximum charge current of 1.25 A suits single-cell Li-Ion packs in the 1000–2500 mAh range — enough for a portable medical device or a handheld scanner to charge in under two hours. The battery regulation voltage tops out at 4.44 V, which covers standard 4.2 V cells plus the higher-voltage 4.35 V and 4.4 V chemistries used in some high-density smartphone and tablet packs. Fault protection includes over-temperature and over-voltage shutdown, so the charger can sit on the board without a separate supervisor IC in most designs. ## I²C control: current, timer, voltage all programmable Unlike a fixed-function charger where the resistor divider sets the float voltage, the BQ24152YFFT lets firmware adjust charge parameters on the fly via I²C. That means the same BOM can handle different cell chemistries by changing a register write, and the host can terminate charging by timer or by current taper without extra pins. ## NRND — plan for a last-time buy or alternate The part is still available for existing production runs, but TI is not actively supporting new design-ins. ## 20-DSBGA — fine-pitch layout considerations The 20-DSBGA package (0.4 mm pitch, 0.25 mm ball diameter) requires a controlled solder-paste stencil and a reflow profile matched to the board thickness.","metaTitle":"BQ24152YFFT Li-Ion Charger, 1.25 A, I²C, NRND","metaDescription":"Texas Instruments BQ24152YFFT single-cell Li-Ion/Polymer charger, 1.25 A max, I²C programmable, 20-DSBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"20-UFBGA, DSBGA","Product Status":"Not For New Designs","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":"BQ24152","Battery Pack Voltage":"4.44V (Max)","Charge Current - Max":"1.25A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current, Timer, Voltage","Voltage - Supply (Max)":"6V","Supplier Device Package":"20-DSBGA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.8871","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/69333d5f699f151d9f7b2dd9315e85bc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ24152YFFT obsolete?","answer":"It is not fully discontinued, but TI is winding down support — existing production can continue, but new designs should look at the current-generation BQ2415x or BQ242xx family for a pin-compatible replacement."},{"question":"Is BQ24152YFFT compatible with 4.2 V Li-ion cells?","answer":"Yes.
