For a design running on a 5V bus — say, a USB VBUS or a 5V peripheral power rail — the TPS25221DRVR sits directly on the rail. ## 2A continuous output — load budget check Rated for 2A continuous output. That sets the ceiling for the load this switch can carry continuously without thermal shutdown. If your downstream circuitry draws 1.5A peak, the 2A rating gives about 25% headroom — comfortable for most applications. For loads exceeding 2A, a higher-rated part in the TPS25221 family would be needed. ## ±6% accuracy — current-limit threshold tolerance The current-limit accuracy is specified at ±6%. That means the actual trip point could be as low as 1.88A or as high as 2.12A on a 2A nominal setting. For overcurrent protection designs, this tolerance band must be factored into the load budget to avoid nuisance trips or insufficient protection. That covers the full industrial temperature grade and extends into under-hood automotive and outdoor telecom enclosures where ambient temperatures can push 85°C to 105°C. The 125°C ceiling means the part can sit near a hot power supply or motor controller without derating prematurely. ## 6-WSON (2x2) package — footprint and thermal pad Supplied in a 6-WSON package with an exposed pad — 2 mm x 2 mm body.","metaTitle":"TPS25221DRVR Current Switch, 2A, 2.5-5.5V, Active","metaDescription":"TI TPS25221DRVR current switch with ±6% accuracy, 2A output, 2.5V-5.5V 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); Cut Tape (CT)","Accuracy":"±6%","Function":"Current Switch","Mounting Type":"Surface Mount","Package / Case":"6-WDFN Exposed Pad","Product Status":"Active","Sensing Method":"-","Voltage - Input":"2.5V ~ 5.5V","lifecycle_stage":"eol_hot","Current - Output":"2A","Base Product Number":"TPS25221","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"6-WSON (2x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/df7c37d2743b5f5a6bef1958d9dd07f6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS25221DRVR/alternatives.json"},"ai":{"faq":[{"question":"Can TPS25221DRVR be used for 5V input applications?","answer":"Yes — the input voltage range is 2.5V to 5.5V, so it works directly on 5V rails without any external level shifting."},{"question":"What is the difference between TPS25221 and TPS25221DRVR?","answer":"The base product number TPS25221 covers multiple package and reel options.
