The maximum charge current is 1.25 A, and the battery regulation voltage tops out at 4.44 V. Over-temperature and over-voltage fault protection are integrated, so the charger can handle fault conditions without a separate supervisor IC. The I²C interface is the main reason to pick this part over a pin-strap charger. The host can adjust the charge current on the fly to match a weak USB source or a higher-current wall adapter, and the timer can be set to match the battery capacity. That saves a resistor divider and a GPIO on the MCU. The trade-off is that the system firmware must initialize the charger after power-up; a fixed-function part would start charging immediately with no software dependency. The 20-DSBGA package is a fine-pitch BGA requiring controlled reflow and X-ray inspection for solder-joint verification. It does not carry AEC-Q100 qualification, so it is not specified for automotive cabin or engine-bay environments. The -30°C low end is useful for cold-weather field gear but not for avionics or downhole tools. The base product number is BQ24153, so any future die revisions will carry the same base number with a different suffix.","metaTitle":"TI BQ24153AYFFT Li-Ion Battery Charger IC, I²C, 1.25A","metaDescription":"Texas Instruments BQ24153AYFFT single-cell Li-Ion/Polymer charger with I²C interface, 1.25A max charge current, over-temp and over-voltage protection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"$7.2600","priceTiers":[{"qty":1,"price":"$7.26000","currency":"USD"},{"qty":10,"price":"$6.55400","currency":"USD"},{"qty":25,"price":"$6.24960","currency":"USD"},{"qty":100,"price":"$5.42640","currency":"USD"},{"qty":250,"price":"$5.18256","currency":"USD"},{"qty":500,"price":"$4.72526","currency":"USD"},{"qty":1250,"price":"$4.31400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8333ed4f6741e67d65ac076ac876724f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24153AYFFT/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to BQ24153AYFFT?","answer":"The BQ24153 family shares the same base product number. Pin-compatible siblings within the BQ24153 family include other suffix variants with the same 20-DSBGA footprint. The BQ24153AYFFT is the specific I²C-programmable variant; a fixed-function sibling would have a different suffix but may share the pinout.
