The 95 mOhm typical Rds(on) sets the conduction loss floor. The 3:4 input-to-output ratio means three control inputs manage four switch outputs, a typical mapping for dual-slot PCMCIA controllers. ## Fault protection and interface Built-in fault protection includes fixed current limiting and over-temperature shutdown, so the switch self-limits under a shorted card or thermal overload without external sense resistors. A status-flag output reports fault conditions back to the host controller. Control is via a serial interface — the host writes the output-enable and slot-select bits through a serial protocol, reducing the GPIO count on the system controller compared to a parallel-controlled switch.","metaTitle":"TPS2224DBR PCMCIA Power Switch, 95 mOhm, 4 Outputs, Obsolete","metaDescription":"Texas Instruments TPS2224DBR PCMCIA switch, 4 outputs at 1A each, 95 mOhm Rds(on), 3.3V/5V/12V load.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Features":"Status Flag","Interface":"Serial","Input Type":"-","Output Type":"-","Switch Type":"PCMCIA Switch","Rds On (Typ)":"95mOhm","Mounting Type":"Surface Mount","Package / Case":"24-SSOP (0.209\\\", 5.30mm Width)","Product Status":"Obsolete","Voltage - Load":"3.3V, 5V, 12V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"4","Base Product Number":"TPS222","Output Configuration":"High Side","Ratio - Input:Output":"3:4","Operating Temperature":"-40°C~85°C(TA)","Current - Output (Max)":"1A","Supplier Device Package":"24-SSOP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.8700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0bf7cbe9a335cba828e1ec7140083d7e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2224DBR/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy TPS2224DBR?","answer":"The TPS2224DBR is obsolete and no longer in production."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2224DBR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2224DBR when reusing this data.
