Its maximum charge current of 2.5 A suits fast charging of 3.7 V battery packs in smartphones, tablets, and handheld instruments. The USB interface lets the IC negotiate input power from a standard USB port or dedicated charger adapter, simplifying the power path in space-constrained designs. Built-in fault protection against over-temperature and short-circuit means the IC can handle fault conditions without external supervisory components — a practical advantage when the charger sits on a flex cable near the battery connector. ## Thermal and package reality for the layout The 24-VFQFN exposed pad package — 4 mm × 4 mm — demands a thermal via array under the pad to pull heat into the ground plane. At 2.5 A charge current, the power dissipation in the internal FET can push junction temperature above 85 °C if the PCB copper area is skimped. Surface-mount assembly is standard; the 24-VQFN footprint is common and reworkable with a hot-air station. ## Active production — sourcing posture We source this device per RFQ — confirm your target quantity and we will provide a current price and lead-time quote. The active lifecycle removes the urgency of a last-time buy, but single-source risk remains; keep an eye on TI's PCN notifications if your production run extends beyond 18 months.","metaTitle":"BQ24165RGER Texas Instruments Li-Ion Charger IC – 2.5A, USB","metaDescription":"Texas Instruments BQ24165RGER single-cell Li-Ion charger IC with USB interface, 2.5A max charge current, over-temp and short-circuit 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":"USB","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Short Circuit","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24165","Battery Pack Voltage":"3.7V","Charge Current - Max":"2.5A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"10V","Supplier Device Package":"24-VQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/31ac4412c7aabe3330da0de5183117ec.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ24165RGER compatible with 3.7 V Li-ion batteries like 18650 cells?","answer":"Yes.
