The device integrates over-temperature and short-circuit fault protection, and offers programmable charge current and timer settings via external components. For a BOM that requires this charger IC, the procurement path is through verified independent distributors who can source new-old-stock or qualified surplus lots. The 8-HVSSOP package and 500 mA charge-current spec are the critical matching points when evaluating any alternate or replacement part. ## Package and footprint — 8-HVSSOP with exposed pad The device is supplied in an 8-HVSSOP package (3.00 mm width, exposed pad), surface-mount, on Tape & Reel. The exposed thermal pad requires a solderable ground plane on the PCB for adequate heat dissipation during charging.","metaTitle":"BQ24203DGNRG4 Li-Ion Charger IC, 500 mA, 8-HVSSOP, Obsolete","metaDescription":"Texas Instruments BQ24203DGNRG4 single-cell Li-Ion/Polymer charger IC, max 500 mA charge current, 4.1V battery pack voltage, 8-HVSSOP package.","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":"BQ24203","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 maximum charge current of BQ24203DGNRG4?","answer":"The maximum charge current is 500 mA, delivered as a constant-current charge for single-cell Li-Ion or Li-Polymer batteries.
