Two outputs handle the 1.5 V rail and one handles the 3.3 V rail, matching the power-up sequencing that an ExpressCard controller expects. Each output is rated for 1.3 A continuous, and the typical on-resistance is 45 mOhm. ## Fault protection and status feedback Built-in current limiting (fixed threshold) and over-temperature protection guard the switch and the downstream load against shorts or overcurrent events. A power-good output and a status flag give the host controller visibility into the switch state — useful for sequencing or fault logging.","metaTitle":"TPS2231PWR Texas Instruments ExpressCard Switch, 45 mOhm","metaDescription":"Texas Instruments TPS2231PWR ExpressCard power switch, 3 outputs, 1.3 A, 45 mOhm Rds(on), -40 to 85°C, 20-TSSOP.","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)","Features":"Power Good, Status Flag","Interface":"-","Input Type":"-","Output Type":"-","Switch Type":"ExpressCard™ Switch","Rds On (Typ)":"45mOhm","Mounting Type":"Surface Mount","Package / Case":"20-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Voltage - Load":"1.5V, 3.3V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"3","Base Product Number":"TPS2231","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~85°C(TA)","Current - Output (Max)":"1.3A","Supplier Device Package":"20-TSSOP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6695","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/72301408950e308afbbf2507f3231a23.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2231PWR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2231PWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2231PWR when reusing this data.
