It handles the 3.3 V, 5 V, and 12 V rails typical of PCMCIA card slots, switching up to 1 A per output through a 95 mOhm typical Rds(on) pass element. At 1 A per output, the 95 mOhm typical on-resistance drops about 95 mV and dissipates 95 mW per channel. ## Protection set — fixed current limit and thermal shutdown The TPS2224ADBG4 includes fixed current limiting and over-temperature protection on each output. The current limit is a fixed threshold — no external resistor sets it — so the 1 A continuous rating is the design ceiling. If a card draws past the limit or the die hits the thermal trip, the output latches off and the status flag asserts through the serial interface. ## 3:4 input-to-output ratio — supply mapping matters The 3:4 input-to-output ratio means three supply inputs (3.3 V, 5 V, 12 V) are distributed across four outputs. Not every output can independently select a rail — the mapping is fixed per the PCMCIA standard. Verify the slot power sequencing requirements against the TPS2224's internal mux before committing the BOM.","metaTitle":"TPS2224ADBG4 PCMCIA Power Switch, 4 Outputs, 95 mOhm","metaDescription":"Texas Instruments TPS2224ADBG4 PCMCIA switch array with 4 high-side outputs, 95 mOhm typical Rds(on), 3.3V/5V/12V load support.","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)","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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/85b5b56277dd039b6836f3d0733598e6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2224ADBG4/alternatives.json"},"ai":{"faq":[{"question":"Does TPS2224ADBG4 have overcurrent and thermal protection?","answer":"Yes, it includes fixed current limiting and over-temperature protection on each output, with a status flag reported through the serial interface."},{"question":"Is TPS2224ADBG4 compatible with 3.3V PCMCIA cards?","answer":"Yes, the 3.3 V load rail is one of the three supported supply inputs, making it compatible with 3.3 V PCMCIA cards."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2224ADBG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2224ADBG4 when reusing this data.
