It regulates the battery voltage to 4.2 V and delivers a constant charge current programmable up to 500 mA via an external resistor. The part integrates over-temperature and short-circuit fault protection, reducing the external component count for a compact charger section. ## 13.5 V input ceiling and thermal design The maximum supply voltage is 13.5 V, so the input rail must be regulated below that — a 12 V bus or a 5 V USB supply works directly, but an unregulated 15 V wall adapter exceeds the rating. ## Programmable current and timer Two programmable features — charge current and charge-termination timer — are set with external resistors. The constant-current charging profile suits single-cell Li-Ion and Li-Polymer chemistries without needing a separate system processor to manage the charge cycle. The timer provides a safety backup if the battery never reaches the 4.2 V regulation threshold. ## Active production, sourced to order No official second-source or pin-compatible alternate is listed in the TI portfolio, so the BQ24200 is the sole direct fit for this BOM position.","metaTitle":"BQ24200DGNR Li-Ion Charger IC, 500 mA, 8-HVSSOP","metaDescription":"Texas Instruments BQ24200DGNR single-cell Li-Ion/Polymer charger, 500 mA max charge current, 13.5V input, -40°C to 125°C.","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)","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width) Exposed Pad","Product Status":"Active","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":"BQ24200","Battery Pack Voltage":"4.2V","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":"$3.6750","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8d269c85a61d814b6ccabe42b85d2ae7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does BQ24200DGNR require external components?","answer":"Yes — the charge current and termination timer are set by external resistors.
