It integrates four high-side outputs with a 3:4 input-to-output ratio — meaning three supply inputs are distributed across four output channels, matching the PCMCIA standard's VCC and VPP power distribution. A serial interface controls the output configuration, and the Status Flag output provides a real-time feedback signal to the host controller. When the output is within regulation, the flag is asserted; if a fault — over-current or over-temperature — is detected, the flag de-asserts, allowing the system to initiate a card reset or power-down sequence. ## 95 mOhm Rds(on) — the voltage-drop budget Each output is rated for 1 A continuous maximum, with a typical on-resistance of 95 mOhm. At full load, that's a 95 mV drop — negligible on the 12 V rail, but a meaningful fraction of the 3.3 V supply to the card. The 24-SSOP package (0.209-inch body width, 5.30 mm body height) dissipates that heat through the lead frame; no external heatsink is required in normal ambient conditions. No external Vcc supply is needed — the switch is self-powered from the load rails.","metaTitle":"TPS2224DB PCMCIA Power Switch, 4 Outputs, 95 mOhm, Active","metaDescription":"Texas Instruments TPS2224DB PCMCIA switch, 4 high-side outputs, 95 mOhm Rds(on), supports 3.3V/5V/12V loads, Status Flag, active lifecycle, 24-SSOP.","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":"Tube","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":"Active","Voltage - Load":"3.3V, 5V, 12V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"4","Base Product Number":"TPS2224","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":"$4.9264","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fd8477305e59097cdd3e981440f521e7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2224DB/alternatives.json"},"ai":{"faq":[{"question":"Does TPS2224DB support 12V load?","answer":"Yes."},{"question":"What is the TPS2224DB used for?","answer":"It is a PCMCIA power switch — a four-output high-side switch designed to route 3.3 V, 5 V, and 12 V to PC Card slots in embedded systems, laptops, docking stations, and telecom line cards that use the PCMCIA / CardBus interface."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2224DB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2224DB when reusing this data.
