The switch integrates adjustable current limiting, over-temperature protection, and undervoltage lockout (UVLO), with a status flag output to signal fault conditions. ## Slew rate control and fault protection Slew-rate controlled turn-on limits inrush current into capacitive loads, reducing supply droop on the upstream rail. The adjustable current-limit threshold is set with an external resistor between the ILIM pin and ground, allowing the designer to tailor the trip point below the 1.5 A maximum. Over-temperature protection shuts off the switch if the junction exceeds the safe operating area, and UVLO prevents the switch from turning on when the input supply is too low.","metaTitle":"TPS2553DBVR-1 Power Distribution Switch, 1.5A, SOT-23-6","metaDescription":"Texas Instruments TPS2553DBVR-1 high-side power switch, 85 mOhm Rds(on), 1.5A max output, adjustable current limit, SOT-23-6.","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)","Features":"Slew Rate Controlled, Status Flag","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"85mOhm","Mounting Type":"Surface Mount","Package / Case":"SOT-23-6","Product Status":"Active","Voltage - Load":"2.5V ~ 6.5V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Adjustable), Over Temperature, UVLO","Number of Outputs":"1","Base Product Number":"TPS2553","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~150°C(TJ)","Current - Output (Max)":"1.5A","Supplier Device Package":"SOT-23-6","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7493475375b8e2a9cc27f8a6d10c07e3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2553DBVR-1/alternatives.json"},"ai":{"faq":[{"question":"What is the exact difference between TPS2553DBVR-1 and TPS2553DBVR?","answer":"The TPS2553DBVR-1 and TPS2553DBVR share the same base product number TPS2553, package (SOT-23-6), and key ratings (1.5 A, 85 mOhm, adjustable current limit). The '-1' suffix typically indicates a specific factory-programmed current-limit threshold or a minor revision; the datasheet should be consulted for the exact threshold difference, as the pinout and footprint are identical."},{"question":"Can TPS2553DBVR-1 be used as a replacement for TPS2553DBVR?","answer":"Yes, the TPS2553DBVR-1 is pin-compatible and functionally equivalent to the TPS2553DBVR in the same SOT-23-6 package. The only difference is the factory-set current-limit threshold; verify that the '-1' variant's limit matches your design requirement before substituting."},{"question":"Does TPS2553DBVR-1 have adjustable current limit and how to set it?","answer":"Yes, the TPS2553DBVR-1 features an adjustable current limit. An external resistor connected from the ILIM pin to ground sets the threshold; the resistor value is chosen per the formula in the datasheet to trip below the 1.5 A maximum output current."},{"question":"What is the maximum output current for TPS2553DBVR-1?","answer":"The TPS2553DBVR-1 is rated for a maximum continuous output current of 1.5 A."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2553DBVR-1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2553DBVR-1 when reusing this data.
