The supply can go up to 13.5V, which covers typical USB or adapter inputs. The chip integrates fault protection against overcurrent, overtemperature, and overvoltage, and lets you program both the charge current and voltage via I²C. The BQ25619ERTWR comes in a 24-WFQFN Exposed Pad package, with the supplier device package designated as 24-WQFN (4x4). Texas Instruments is the sole manufacturer. No official successor or second-source has been announced, so this remains the current production part for the BQ25619 series.","metaTitle":"BQ25619ERTWR - Texas Instruments 1-Cell Li-Ion Battery","metaDescription":"Texas Instruments BQ25619ERTWR: 1-cell Li-Ion/Polymer charger, I²C interface, 1.8A max charge current, 4.52V battery pack voltage, industrial temp range -40°C","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":"24-WFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ25619","Battery Pack Voltage":"4.52V","Charge Current - Max":"1.8A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current, Voltage","Voltage - Supply (Max)":"13.5V","Supplier Device Package":"24-WQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0600","priceTiers":[{"qty":1,"price":"$3.06000","currency":"USD"},{"qty":10,"price":"$2.75000","currency":"USD"},{"qty":25,"price":"$2.59960","currency":"USD"},{"qty":100,"price":"$2.25300","currency":"USD"},{"qty":250,"price":"$2.13748","currency":"USD"},{"qty":500,"price":"$1.91796","currency":"USD"},{"qty":1000,"price":"$1.63500","currency":"USD"},{"qty":3000,"price":"$1.63500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8293edb850af4a6b991d7345e6367f9b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25619ERTWR/alternatives.json"},"ai":{"faq":[{"question":"Can the BQ25619ERTWR charge a 2-cell battery pack?","answer":"No. The BQ25619ERTWR is designed for a single Li-Ion/Polymer cell only. The battery pack voltage is set to 4.52V, which is typical for a single cell. For 2-cell packs you would need a charger with a higher cell count, such as the BQ25629 series."},{"question":"What is the maximum charge current of the BQ25619ERTWR?","answer":"The maximum programmable charge current is 1.8A. The current is constant and programmable via I²C, so you can set it lower to match the battery's recommended charge rate or to stay within thermal limits."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ25619ERTWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ25619ERTWR when reusing this data.
