Each output is rated for 1 A continuous, with a typical Rds(on) of 95 mOhm, so the voltage drop at full load stays under 100 mV — clean power for the card's logic and programming rails. A serial interface handles the switch control, and the status flag output tells the host if the output is on or if a fault has tripped — useful for the firmware engineer debugging a dead slot. ## Protection and temperature range Built-in fault protection includes current limiting (fixed threshold) and over-temperature shutdown — if a card shorts or the board runs hot, the switch folds back before the traces or the card itself let the smoke out. It comes in a 24-HTSSOP package — that is a TSSOP with an exposed thermal pad underneath. The pad needs a good solder joint to the board's ground plane for the part to shed heat from the 1 A outputs. The rework tech should set the hot-air profile for a pad-under package; the exposed pad wicks heat fast. The TPS2204APWPRG4 is listed as obsolete. For a board that needs this exact PCMCIA switch, the only channel is the independent surplus market.","metaTitle":"TPS2204APWPRG4 PCMCIA Power Switch, 4 Outputs, 95 mOhm","metaDescription":"Texas Instruments TPS2204APWPRG4 PCMCIA switch IC, 4 outputs, 95 mOhm Rds(on), 3.3V/5V/12V load, industrial temp -40 to 85°C.","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)","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","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":"24-HTSSOP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f523f37b4553b26ad5faf908dd586fa2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2204APWPRG4/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy TPS2204APWPRG4 and get a price?","answer":"This part is obsolete and no longer in production.
