It integrates four high-side outputs rated at 1 A each, with a typical on-resistance of 95 mOhm per channel. A serial interface handles output configuration and status readback, while the integrated Status Flag pin reports fault conditions (overcurrent or overtemperature) to the host controller without polling. At 1 A per output, the 95 mOhm typical Rds(on) yields ~95 mW dissipation per channel. With all four outputs loaded, the total die dissipation is ~380 mW — manageable in the 24-SSOP package provided the board has adequate copper for heat spreading. The fixed current-limiting threshold (no external sense resistor) protects the PCMCIA card and host wiring against shorts; the over-temperature shutdown catches thermal runaway if the die exceeds the safe junction limit. The supplier device package is 24-SSOP. Tube shipping is the default; if your pick-and-place feeder requires Tape & Reel, confirm the reel option with your distributor at quote time.","metaTitle":"TPS2223ADB PCMCIA Power Switch, 95mOhm, 4 Outputs, 24-SSOP","metaDescription":"Texas Instruments TPS2223ADB PCMCIA switch IC, 4 high-side outputs at 1A each, 95mOhm Rds(on), serial interface, status flag, -40 to 85°C.","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","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"4","Base Product Number":"TPS2223","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":"$4.4916","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/85b5b56277dd039b6836f3d0733598e6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2223ADB/alternatives.json"},"ai":{"faq":[{"question":"What is the Rds(on) of TPS2223ADB?","answer":"The typical on-resistance is 95 mOhm per output.
