At 3A max charge current, this IC can fill a typical 18650 cell (3000–3500 mAh) in about an hour — limited by the cell's own C-rate. The constant-current phase is programmable via I²C, so the same BOM can charge a 500 mAh coin cell at a lower current without hardware change. Supply voltage max is 6.2V, which means the part works from a 5V USB rail or a standard 5V wall adapter without a pre-regulator. The battery pack voltage is fixed at 4.2V, matching the termination voltage for standard Li-Ion and Li-Polymer cells. ## Package and thermal considerations for layout The fault protection block includes over-current, over-temperature, and over-voltage — these are hardwired, not reliant on the I²C controller being active.","metaTitle":"BQ24296RGER – Texas Instruments Li-Ion Battery Charger IC","metaDescription":"BQ24296RGER from Texas Instruments: single-cell Li-Ion/Polymer charger, 3A max charge current, I²C interface, 24-VQFN exposed pad.","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-VFQFN 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":"BQ24296","Battery Pack Voltage":"4.2V","Charge Current - Max":"3A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"6.2V","Supplier Device Package":"24-VQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.0400","priceTiers":[{"qty":1,"price":"$4.04000","currency":"USD"},{"qty":10,"price":"$3.63300","currency":"USD"},{"qty":25,"price":"$3.43440","currency":"USD"},{"qty":100,"price":"$2.97650","currency":"USD"},{"qty":250,"price":"$2.82384","currency":"USD"},{"qty":500,"price":"$2.53382","currency":"USD"},{"qty":1000,"price":"$2.16000","currency":"USD"},{"qty":3000,"price":"$2.16000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2724f87a310e8162308569a356dcac03.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24296RGER/alternatives.json"},"ai":{"faq":[{"question":"Is BQ24296RGER equivalent to BQ24295?","answer":"Both are single-cell chargers from the same base family (BQ24296 vs BQ24295) with the same 24-VQFN package. The key difference is the I²C register map and charge algorithm — confirm your firmware target before swapping. No official cross-reference is published by TI."},{"question":"Can BQ24296RGER be used with a single 18650 Li-ion cell?","answer":"Yes. The charger supports one Li-Ion or Li-Polymer cell with a 4.2V pack voltage. The 3A max charge current is well within the typical 1C rate of a standard 18650 cell. Program the current via I²C to match the cell's datasheet rating."},{"question":"Is BQ24296RGER compatible with lithium polymer batteries?","answer":"Yes. The battery chemistry is listed as Lithium Ion/Polymer, so it works with both Li-Ion and Li-Polymer cells. The 4.2V pack voltage is the standard termination for these chemistries."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24296RGER","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24296RGER when reusing this data.
