It integrates four high-side MOSFET switches with a 3:4 input-to-output ratio, meaning three control inputs manage four output channels — a mapping that matches the standard PCMCIA slot power-control scheme. Each output is rated for 1 A continuous, and the switch can source 3.3 V, 5 V, or 12 V to the load — covering both the logic supply and the 12 V programming voltage required by older flash-memory PC Cards. ## Built-in fault protection and status reporting Fixed current limiting and over-temperature shutdown protect the switch and the card from short-circuit or overcurrent events without requiring an external sense resistor. A Power Good output and a Status Flag provide digital feedback to the host controller, confirming that the output voltage has settled within regulation or flagging a fault condition. No official replacement or cross-reference part number is listed by the manufacturer, so any substitution requires a form-fit-function evaluation of alternative PCMCIA switch ICs from the same or other vendors. Available inventory is limited to existing stock in the independent distribution channel. Housed in a 30-pin SSOP package with a 0.209-inch body width and 5.30 mm height, the TPS2201IDFR is a surface-mount device that fits the standard PCMCIA controller footprint used in late-1990s through mid-2000s portable designs.","metaTitle":"TPS2201IDFR PCMCIA Power Switch, 4-Channel, 1A, Obsolete","metaDescription":"Texas Instruments TPS2201IDFR PCMCIA switch IC, 4 high-side outputs at 1A each, supports 3.3V/5V/12V loads.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Power Good, Status Flag","Interface":"Parallel","Input Type":"-","Output Type":"-","Switch Type":"PCMCIA Switch","Rds On (Typ)":"160mOhm (Max)","Mounting Type":"Surface Mount","Package / Case":"30-SSOP (0.209\\\", 5.30mm Width)","Product Status":"Obsolete","Voltage - Load":"3.3V, 5V, 12V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"4","Base Product Number":"TPS220","Output Configuration":"High Side","Ratio - Input:Output":"3:4","Operating Temperature":"-40°C~85°C(TA)","Current - Output (Max)":"1A","Supplier Device Package":"30-SSOP","Voltage - Supply (Vcc/Vdd)":"4.75V ~ 5.25V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.4000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4e85e764b113f753bdb278195231f158.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2201IDFR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for TPS2201IDFR?","answer":"Texas Instruments has not published an official replacement or cross-reference for the TPS2201IDFR.
