It integrates current limiting and over-temperature fault protection, with a fixed current limit at 1 A per output, and supports load voltages of 3.3 V, 5 V, and 12 V — covering the three standard PCMCIA power rails. A 3:2 input-to-output ratio means three control inputs select which of the two outputs is active, simplifying host-side GPIO allocation. The parallel interface eliminates the need for a serial bus, keeping the control logic straightforward for legacy PCMCIA controllers or CPLD-based glue logic. This keeps the slot supply within the PCMCIA tolerance band without requiring external pass transistors or separate regulators. The low Rds(on) also limits self-heating: at 1 A, dissipation is 70 mW per channel, well within the thermal capacity of the HTSSOP package with the exposed pad soldered to a PCB copper plane. The fixed current limit at 1 A per output protects the host supply and the card connector against overcurrent events. Combined with the over-temperature shutdown, the switch can survive a sustained short on the slot without damage — the thermal protection cycles the output until the fault clears. ## Package and thermal: the HTSSOP exposed-pad requirement Without that, junction temperature rises above the 85°C ambient limit at full load. The 20-PowerTSSOP body is 4.40 mm wide.","metaTitle":"Texas Instruments TPS2211APWR PCMCIA Power Switch, 70 mOhm","metaDescription":"Texas Instruments TPS2211APWR PCMCIA switch, 2 outputs at 1 A each, 70 mOhm typical Rds(on), 3.3V/5V/12V load, -40°C to 85°C, active production, sourced to","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":"Status Flag","Interface":"Parallel","Input Type":"-","Output Type":"-","Switch Type":"PCMCIA Switch","Rds On (Typ)":"70mOhm","Mounting Type":"Surface Mount","Package / Case":"20-PowerTSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","Voltage - Load":"3.3V, 5V, 12V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"2","Base Product Number":"TPS2211","Output Configuration":"High Side","Ratio - Input:Output":"3:2","Operating Temperature":"-40°C~85°C(TA)","Current - Output (Max)":"1A","Supplier Device Package":"20-HTSSOP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1235","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/602bd67fdbd9862c9eef0b189908e98c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2211APWR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2211APWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2211APWR when reusing this data.
