That 2A limit is the practical charging speed for a single 18650 or pouch cell in a handheld or portable device — enough to charge a 2000 mAh cell in about an hour without pushing the thermal budget of the 20-VFQFN exposed-pad package. ## Charge current set by external resistor — no I2C needed The charge current is constant and programmable via an external resistor. That means you set the rate with a single passive component, not a serial bus — useful for designs where the charger runs autonomously from the system MCU. The programmable features also include a timer, which acts as a safety timeout if the battery never reaches the 4.2V full-charge voltage.","metaTitle":"BQ24100RHLR Li-Ion Charger IC, 2A Max, 16V Input, Active","metaDescription":"Texas Instruments BQ24100RHLR single-cell Li-Ion/Polymer charger IC. 2A max charge current, 16V supply, -40°C to 85°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":"bqSWITCHER™","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"20-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":"BQ24100","Battery Pack Voltage":"4.2V","Charge Current - Max":"2A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"16V","Supplier Device Package":"20-VQFN (3.5x4.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.7000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/26d08c6a9886ba7ed4911c20d19d787e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the charge current limit for BQ24100RHLR?","answer":"The maximum charge current is 2A, set by an external resistor. The charger is constant-current programmable, so you choose the rate below that ceiling with a single resistor value."},{"question":"Can I replace BQ24103 with BQ24100RHLR?","answer":"The BQ24100 and BQ24103 are different variants within the same bqSWITCHER™ family. Pin compatibility depends on the specific feature set — the BQ24100 lacks some of the BQ24103's additional features. Verify the pinout and feature differences against your design before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24100RHLR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24100RHLR when reusing this data.
