Input supply range extends to 17V, accommodating a wide variety of wall adapters or USB-PD sources without an external pre-regulator. The constant-current charge profile is programmable via an external resistor, giving the BOM engineer direct control over charge rate vs. thermal budget. ## Industrial temperature grade and fault protection Integrated fault protection covers over-current, over-temperature, and over-voltage conditions, reducing external supervisory circuitry and simplifying safety certification.","metaTitle":"BQ24133RGYT Li-Ion/Polymer Charger IC, 2.5A, 1-3 Cells","metaDescription":"Texas Instruments BQ24133RGYT: Li-Ion/Polymer battery charger, 2.5A max, 1-3 cells, 17V input, -40°C to 85°C, 24-VFQFN.","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":"-","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1 ~ 3","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24133","Battery Pack Voltage":"4.2V","Charge Current - Max":"2.5A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current","Voltage - Supply (Max)":"17V","Supplier Device Package":"24-VQFN (5.5x3.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.6900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f10abe22066dd647082bae4c7b264a00.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24133RGYT/alternatives.json"},"ai":{"faq":[{"question":"Is BQ24133RGYT compatible with 3.7V lithium batteries?","answer":"Yes.
