It integrates over-temperature fault protection and offers programmable charge current and charge timer via external components. ## Obsolete — sourcing through independent distribution The BQ24003RGWR is listed as Obsolete in the lifecycle record. ## Charge profile and supply rail limits The charger operates from a supply voltage up to 10V maximum, which covers standard 5V USB or wall-adapter inputs with margin. The constant-current charge algorithm is fixed — no PWM or switching stage — so thermal dissipation at 1.2A charge current must be managed via the exposed pad and PCB copper area. Operating temperature is rated from -40°C to 70°C, which suits consumer and most industrial portable equipment but does not cover extended automotive or high-temp environments. The programmable timer provides a safety backup to terminate charging if the battery does not reach full voltage within the set window.","metaTitle":"BQ24003RGWR Li-Ion Charger IC, 1.2A, 4.2V, 20-VQFN, Obsolete","metaDescription":"Texas Instruments BQ24003RGWR single-cell Li-ion linear charger, 1.2A max charge current, 4.2V battery pack voltage, 20-VQFN exposed pad.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"20-VQFN Exposed Pad","Product Status":"Obsolete","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant","Base Product Number":"BQ24003","Battery Pack Voltage":"4.2V","Charge Current - Max":"1.2A","Operating Temperature":"-40°C~70°C(TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"10V","Supplier Device Package":"20-VQFN (5x5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$50.4500","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2fc9494cc966b3ee583a1076b838c75e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy BQ24003RGWR?","answer":"No stock-holding or immediacy claim is made."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24003RGWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24003RGWR when reusing this data.
