Maximum charge current is 2.5 A, which suits portable devices needing a fast charge cycle without pushing into the 3 A+ class that demands a larger inductor and thermal budget. At 2.5 A the part charges a typical 3.7 V single-cell pack at roughly 1 C for a 2500 mAh battery, completing a full cycle in about an hour. The constant-current phase is programmable via I²C, so the same PCB can serve multiple SKUs by adjusting the charge current in firmware — no resistor change. The 24-VFQFN package with exposed pad (4x4 mm) must have its thermal pad soldered to a copper plane; without that the junction temperature rises above the 85°C operating ceiling at sustained 2.5 A. ## Protection and temperature range for industrial portable gear Built-in over-temperature and over-voltage fault protection means the charger shuts down before the battery or the IC itself reaches a damage threshold — no external supervisor needed. Supply maximum is 10 V, so a 5 V USB bus or a 9 V wall adapter both work without a pre-regulator.","metaTitle":"TI BQ24160ARGER Li-Ion Charger IC, 2.5A Max, I²C, 24-VQFN","metaDescription":"Texas Instruments BQ24160ARGER single-cell Li-Ion/Polymer charger IC with I²C interface, 2.5A max charge current, over-temp/over-voltage protection, -40°C to","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":"I²C","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, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24160","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/efeeca1e0c9fe6989470194ce33990eb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current for BQ24160ARGER?","answer":"The BQ24160ARGER supports a maximum charge current of 2.5 A, programmable via I²C. This is the constant-current ceiling; the actual charge current in a design is set by the host MCU through the I²C register."},{"question":"Is BQ24160ARGER compatible with 2-cell batteries?","answer":"No — the BQ24160ARGER is a single-cell charger (Number of Cells = 1). It is designed for one Li-Ion or Li-Polymer cell in series. A 2-cell pack requires a different charger IC rated for series-cell balancing and higher voltage."},{"question":"Does the package ship as Tape & Reel or Cut Tape?","answer":"The package itself is a 24-VFQFN with exposed pad, 4x4 mm body.
