At the rated 1.5 A continuous output, that resistance drops about 128 mV across the switch — a figure that matters when the downstream load has a tight undervoltage lockout threshold. ## Slew rate control and adjustable current limit Slew rate control limits the output voltage rise time during turn-on, reducing inrush current into capacitive loads. The current limit is adjustable via an external resistor, letting the designer set the trip point below the 1.5 A maximum to protect the load or the wiring. A status flag output asserts low when the switch is in current limit or thermal shutdown, providing a clean fault signal to a GPIO or system monitor. ## 150°C junction — package thermal reality The junction temperature range extends to 150°C, which qualifies the part for under-hood automotive and industrial enclosure environments. At 1.5 A continuous, the 85 mOhm Rds(on) dissipates about 190 mW — within the package capability at 85°C ambient with reasonable board copper, but the margin shrinks at elevated ambient temperatures. The over-temperature protection provides a safety net. ## Protection set: UVLO, over-temperature, adjustable limit Undervoltage lockout (UVLO) holds the switch off until the input voltage rises above the minimum operating threshold, preventing the MOSFET from operating in the linear region. Over-temperature protection shuts down the switch if the die exceeds the thermal limit, with automatic recovery after cooling. The adjustable current limit, set by a resistor to ground, allows the designer to tailor the trip point to the specific load — useful for powering USB ports, sensors, or peripheral rails where the fault current must be clamped below the supply's capacity.","metaTitle":"TI TPS2553DDBVT Power Distribution Switch, 85 mOhm, SOT-23-6","metaDescription":"Texas Instruments TPS2553DDBVT high-side power switch: 1.5 A output, 85 mOhm Rds(on), 2.7-6.5 V load, adjustable current limit, slew rate control, 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":"2.7V ~ 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/bbdec4ec60827e71651cb759b97ad2ab.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2553DDBVT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2553DDBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2553DDBVT when reusing this data.
