For a 2 Ah cell, that same 3 A ceiling still delivers a 0.5 C charge rate — fast enough for most portable equipment without stressing the cell. ## Built-in fault protection cuts external parts Overcurrent, overvoltage, and overtemperature protection are integrated — no separate supervisor or fuse needed. That saves about 20 mm² of board area versus a discrete protection chain, and it eliminates one failure point that a repair bench would otherwise have to trace. ## Dual-chemistry flexibility on one BOM line The charger handles both Li-ion/Li-polymer (4.2 V full-charge) and LiFePO4 cells — the battery pack voltage is set by the external resistor divider. A single BQ25300RTER can serve a product line that ships with either chemistry, reducing inventory complexity. ## Package and footprint: 16-WFQFN (3x3 mm) The 16-WFQFN with exposed pad (3x3 mm body) is a compact surface-mount package.","metaTitle":"BQ25300RTER 1-Cell Li-Ion/LiFePO4 Charger IC, 3 A","metaDescription":"Texas Instruments BQ25300RTER 1-cell battery charger IC supports Li-Ion, Li-Polymer, and LiFePO4 with programmable charge current up to 3 A.","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":"USB","Mounting Type":"Surface Mount","Package / Case":"16-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, Lithium Iron Phosphate","Current - Charging":"Constant - Programmable","Base Product Number":"BQ25300","Battery Pack Voltage":"4.2V","Charge Current - Max":"3A","Operating Temperature":"-40°C ~ 85°C (TA)","Programmable Features":"Current, Timer, Voltage","Voltage - Supply (Max)":"17V","Supplier Device Package":"16-WQFN (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8af7b3b35cf2e808ee671db9344f08cd.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ25300RTER suitable for 1-cell LiFePO4 charging?","answer":"Yes — the BQ25300RTER supports LiFePO4 chemistry alongside Li-ion and Li-polymer.
