The switch is controlled via a serial interface and reports card-present status through a dedicated flag output, matching the PCMCIA power-control protocol used in notebook and embedded card-reader designs. ## Protection scheme — no external sense resistor needed Fault protection includes fixed current limiting and over-temperature shutdown, both built into the die. The current limit is preset — no external sense resistor or trim network — and the thermal foldback prevents the switch from exceeding its safe junction temperature during a sustained overload or short circuit. The input-to-output ratio is 3:4, meaning three control signals manage four output channels, which reduces the GPIO count required from the host controller. The SSOP footprint is a common choice for PCMCIA power controllers in multi-layer PCBs where the card slot sits near the board edge.","metaTitle":"TI TPS2223DBR PCMCIA Power Switch, 4-Ch, 95 mOhm, SSOP-24","metaDescription":"Texas Instruments TPS2223DBR PCMCIA switch, 4 outputs at 1 A each, 95 mOhm Rds(on), fixed current limit, active production.","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-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":"$2.9445","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fd8477305e59097cdd3e981440f521e7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2223DBR/alternatives.json"},"ai":{"faq":[{"question":"Does TPS2223DBR have overcurrent protection?","answer":"Yes, the TPS2223DBR includes fixed current limiting and over-temperature shutdown as built-in fault protections — no external sense resistor is required."},{"question":"What is a PCMCIA switch?","answer":"A PCMCIA switch is a power-distribution IC that controls and protects the supply rails to PC Card slots.
