Fault protection includes over-temperature, over-voltage, reverse current, and short-circuit detection. The USB interface allows direct connection to a standard USB port or a dedicated charger adapter, with the battery pack voltage regulated to 4.1V. ## Active production — no end-of-life risk for automotive programs The base product number is BQ24079; the full order code includes the Q1 suffix indicating AEC-Q100 qualification and the RGTR package code for the 16-VQFN (3x3 mm) exposed pad. ## 16-VFQFN exposed pad — thermal and layout considerations The 16-VFQFN exposed pad (3x3 mm) requires a thermal land on the PCB to dissipate heat from the linear regulator pass element.","metaTitle":"BQ24079QWRGTRQ1 Texas Instruments Automotive Li-Ion Charger","metaDescription":"AEC-Q100 qualified single-cell Li-Ion/Polymer charger IC from TI. 1.5A max charge current, USB interface, 26V input tolerance, -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","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/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24079","Battery Pack Voltage":"4.1V","Charge Current - Max":"1.5A","Operating Temperature":"-40°C~125°C(TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"26V","Supplier Device Package":"16-VQFN (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.5600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9d617152d4f083b0574cd23b8fb6420e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ24079QWRGTRQ1 suitable for automotive battery charging?","answer":"It is designed for single-cell Li-Ion/Polymer packs in automotive infotainment, telematics, and ADAS backup-battery applications."},{"question":"Is BQ24079QWRGTRQ1 compatible with 4.2V Li-ion batteries?","answer":"The battery pack voltage is regulated to 4.1V, so it is intended for cells with a 4.1V charge termination voltage, not standard 4.2V cells.
