Each output is a high-side switch rated for 1 A continuous with a typical on-resistance of 103 mOhm, keeping conduction loss low enough that the 30-SSOP package handles the thermal load without a heatsink in most designs. The parallel interface accepts slot-select and Vcc/Vpp control signals directly from a system controller or PCMCIA host adapter — no serial bus overhead, which simplifies the firmware and reduces latency on card insertion events. ## 103 mOhm Rds(on) and the 1 A output ceiling At 1 A per channel, the 103 mOhm typical Rds(on) produces about 103 mW of self-heating per active output. With all four channels loaded, the total dissipation sits near 0.4 W — within the 30-SSOP's capability in still air at 85°C ambient, but a layout with copper pours under the package helps keep junction temperature below the 125°C absolute maximum. The fixed current-limiting and over-temperature fault protection clamp the output before the die overheats or the card draws more than the 1 A ceiling. A status flag output reports fault conditions back to the host controller — useful for diagnostic logging or for sequencing a card power-down. The 30-SSOP package (5.30 mm body width, 0.65 mm pitch) is a common footprint — the same land pattern used by many TI power-switch and interface parts, which helps consolidate stencils. The supply voltage (Vcc/Vdd) is not required — the switch derives its internal bias from the load rails, so no separate logic supply is needed.","metaTitle":"TPS2205IDB PCMCIA Power Switch, 103 mOhm, 4 Outputs, 30-SSOP","metaDescription":"Texas Instruments TPS2205IDB PCMCIA switch IC, 4 high-side outputs, 103 mOhm typical Rds(on), 1 A per channel, parallel interface, industrial temp -40°C to","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)":"103mOhm","Mounting Type":"Surface Mount","Package / Case":"30-SSOP (0.209\\\", 5.30mm Width)","Product Status":"Active","Voltage - Load":"3.3V, 5V, 12V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"4","Base Product Number":"TPS2205","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)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.0283","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ec947e78298ef43443a0a9084f1076cd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2205IDB/alternatives.json"},"ai":{"faq":[{"question":"What is TPS2205IDB used for?","answer":"It is a PCMCIA power-interface switch that distributes 3.3 V, 5 V, or 12 V to up to four card-slot outputs.
