It delivers a constant charge current up to 500 mA and terminates at a 4.1 V battery pack voltage. The part integrates over-temperature and short-circuit fault protection, and offers programmable charge current and timer via external components. The 500 mA maximum charge current sets the ceiling for how fast a single-cell Li-Ion pack can be charged. ## 8-HVSSOP with exposed pad — rework and thermal reality The 8-HVSSOP package (3.00 mm width, exposed pad) is a small-outline package with a thermal pad underneath. For rework, the exposed pad means you need a hot-air station with a nozzle that covers the whole pad; a standard soldering iron won't get the pad hot enough to reflow. The pin 1 indicator is on the top side — a small dot — so orientation is clear under magnification. ## Supply voltage and operating range The IC accepts a maximum supply voltage of 13.5 V, which covers typical 5 V USB or 12 V wall-adapter inputs. The surface-mount package and tape-and-reel delivery are standard for automated assembly. ## Obsolete — sourcing through independent distribution That means the manufacturer no longer produces the part and has no planned last-time-buy window. New designs should not use this part. No official replacement or pin-compatible successor is listed by TI; any substitute would require a board redesign.","metaTitle":"TI BQ24205DGNR Li-Ion Charger IC, 500 mA, Obsolete","metaDescription":"Texas Instruments BQ24205DGNR single-cell Li-Ion/Polymer linear charger IC, 500 mA max charge current, 8-HVSSOP, obsolete.","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":"BQ24205","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":"$6.8400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d9a2603e1298939b8790cfaa4790a3a5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy BQ24205DGNR?","answer":"The BQ24205DGNR is obsolete from the manufacturer.
