Each output is rated for 1 A continuous with a typical Rds(on) of 95 mOhm, keeping conduction losses low enough that the 24-HTSSOP exposed-pad package can dissipate the heat without forced airflow in most PCMCIA applications. The serial interface controls output sequencing, and the integrated status flag provides a fault-reporting signal back to the host controller for over-current or over-temperature events. ## Protection set — fixed current limit and thermal shutdown Fault protection includes current limiting (fixed threshold) and over-temperature shutdown — no external sense resistor needed, and the part latches off until the fault clears or the enable is cycled. The status flag output (open-drain, active low) asserts during a fault condition, giving the host controller a direct interrupt signal rather than requiring polling of the output voltage.","metaTitle":"TPS2223APWPRG4 PCMCIA Power Switch, 4-Ch, 95 mOhm, Active","metaDescription":"Texas Instruments TPS2223APWPRG4 PCMCIA switch array: 4 high-side outputs, 95 mOhm typical Rds(on), 3.3V/5V load, -40°C to 85°C, 24-HTSSOP.","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":"Serial","Input Type":"-","Output Type":"-","Switch Type":"PCMCIA Switch","Rds On (Typ)":"95mOhm","Mounting Type":"Surface Mount","Package / Case":"24-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","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-HTSSOP","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/TPS2223APWPRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the Rds(on) of TPS2223APWPRG4?","answer":"Typical Rds(on) is 95 mOhm per output channel at nominal load.
