The charge current is constant and programmable up to 1.5 A, with a programmable timer to terminate the charge cycle. The IC integrates over-temperature, over-voltage, reverse-current, and short-circuit fault protection, reducing the external component count for a safe charging solution. ## 1.5 A charge current and thermal envelope The 1.5 A maximum charge current is set by an external resistor; the charge current can be programmed lower to match the thermal budget of the 16-VFQFN exposed-pad package. ## Fault protection and charge termination Over-voltage protection clamps the input to safe levels for the battery; reverse-current blocking prevents the pack from discharging back into the input when the supply is removed. Short-circuit and over-temperature protection shut down the charger under fault conditions without latch-up. The programmable timer provides a backup termination method if the battery never reaches the 4.1 V full-charge threshold — useful for deeply depleted cells or high-impedance connections.","metaTitle":"BQ24079RGTT Li-Ion Charger IC, USB, 1.5A, 16-VQFN","metaDescription":"Texas Instruments BQ24079RGTT single-cell Li-Ion linear charger with USB interface, 1.5 A max charge current, industrial temp range -40°C to 125°C, 16-VQFN","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":"USB","Mounting Type":"Surface Mount","Package / Case":"16-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage, Reverse Current, Short Circuit","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24079","Battery Pack Voltage":"4.1V","Charge Current - Max":"1.5A","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"6.4V","Supplier Device Package":"16-VQFN (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.3800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d0fea2149ca33a1e576a4f585bed3a5b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ24079RGTT compatible with 4.2 V Li-ion batteries?","answer":"The battery pack voltage is specified as 4.1 V, so this part is intended for 4.1 V Li-ion cells, not the more common 4.2 V chemistry. For 4.2 V cells, look at the BQ24075 or similar variants in the family."},{"question":"Does BQ24079RGTT support fast charging?","answer":"Yes, the charge current is programmable up to 1.5 A, which qualifies as fast charging for a typical 1000–1500 mAh single-cell Li-ion pack.
