A status flag output (open-drain, active low) asserts when the switch is in current-limit or thermal-shutdown, which a system microcontroller can read to trigger a retry or log the fault.","metaTitle":"TPS2553DBVT-1 Power Distribution Switch, 85 mOhm, SOT-23-6","metaDescription":"Texas Instruments TPS2553DBVT-1 high-side power switch: 1.5 A output, 85 mOhm Rds(on), 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":"$1.1700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7493475375b8e2a9cc27f8a6d10c07e3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2553DBVT-1/alternatives.json"},"ai":{"faq":[{"question":"How to adjust the current limit on TPS2553DBVT-1?","answer":"The current limit is adjustable via an external resistor connected between the ILIM pin and ground. The datasheet provides a resistor-value table for trip points from 0.5 A up to the 1.5 A maximum output. The resistor sets the reference current that the internal sense amplifier compares against the load current."},{"question":"Can TPS2553DBVT-1 handle 5V input and output continuously?","answer":"Yes. The load voltage range is 2.5 V to 6.5 V, so 5 V continuous operation is well within the rated envelope. The 85 mOhm Rds(on) at 5 V yields about 425 mV drop at 1.5 A — factor that into the downstream rail budget."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2553DBVT-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/TPS2553DBVT-1 when reusing this data.
