The 3:2 input-to-output ratio means you can select which of the three supply voltages (3.3V, 5V, 12V) gets routed to each of the two outputs — the parallel interface picks the rail. Fixed current limiting and over-temperature shutdown are built in — if a card draws more than the limit or the die hits thermal threshold, the switch latches off and the status flag pin goes low. That flag is your first clue which part actually died when the slot goes dead. No separate Vcc/Vdd supply is needed — the switch powers itself from the load rails. That simplifies the board layout: just the 3.3V, 5V, and 12V inputs and the two output pins to the slot connector. Housed in a 16-SSOP (0.209\", 5.30 mm width) surface-mount package, supplied in tube.","metaTitle":"TPS2212IDBG4 PCMCIA Power Switch, 160 mOhm, 16-SSOP","metaDescription":"Texas Instruments TPS2212IDBG4 dual high-side PCMCIA switch, 250 mA per output, 160 mOhm Rds(on), parallel interface, status flag, active lifecycle.","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":"Parallel","Input Type":"-","Output Type":"-","Switch Type":"PCMCIA Switch","Rds On (Typ)":"160mOhm","Mounting Type":"Surface Mount","Package / Case":"16-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":"2","Base Product Number":"TPS2212","Output Configuration":"High Side","Ratio - Input:Output":"3:2","Operating Temperature":"-40°C~85°C(TA)","Current - Output (Max)":"250mA","Supplier Device Package":"16-SSOP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0afcddc1178ae6e7149a23a83cd8b101.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2212IDBG4/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to TPS2212IDBG4?","answer":"No official cross-reference or second-source alternate is listed for this exact order code.
