It integrates over-temperature and short-circuit fault protection, and allows the designer to program the charge current and safety timer via external components. A 500 mA maximum charge current targets single-cell Li-Ion packs in the 500 mAh to 1500 mAh range — think portable medical devices, handheld instruments, or battery-backed IoT edge nodes. The constant-current (CC) charging profile is fixed; the programmable timer prevents overcharge if the battery never reaches the 4.1 V regulation threshold. For larger packs (above 1500 mAh), the charge time at 500 mA becomes impractically long, and a higher-current charger or a switching topology would be the better fit. The BQ24201DGNRG4 carries an Obsolete product status per the manufacturer. If your design is still in the prototype phase, consider evaluating a current-production single-cell Li-Ion charger from TI's portfolio to avoid a future last-time-buy scramble.","metaTitle":"TI BQ24201DGNRG4 Li-Ion Charger IC, 500 mA, Obsolete","metaDescription":"Texas Instruments BQ24201DGNRG4 single-cell Li-Ion/Polymer charger IC, 500 mA max charge current, -40°C to 125°C.","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)","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width) Exposed Pad","Product Status":"Obsolete","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant","Base Product Number":"BQ24201","Battery Pack Voltage":"4.1V","Charge Current - Max":"500mA","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"13.5V","Supplier Device Package":"8-HVSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d9a2603e1298939b8790cfaa4790a3a5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BQ24201DGNRG4?","answer":"For a pin-compatible or function-compatible current-production alternative, review TI's active single-cell Li-Ion charger family — the BQ24201DGNRG4 uses an 8-HVSSOP package with exposed pad, so any replacement should match that footprint and the 500 mA / 4.1 V charging profile."},{"question":"What is the maximum charge current of BQ24201DGNRG4?","answer":"The maximum charge current is 500 mA, delivered as a constant-current charge for a single-cell Li-Ion or Li-Polymer battery with a 4.1 V regulation voltage."},{"question":"What is the difference between BQ24201DGNRG4 and BQ24201DGN?","answer":"The BQ24201DGNRG4 and BQ24201DGN share the same base product number and electrical specifications.
