Each of the four outputs is rated for 1A continuous and is protected by fixed current limiting and over-temperature shutdown, with a serial interface controlling the output configuration in a 3:4 input-to-output ratio. The switch integrates Power Good and Status Flag outputs for monitoring rail integrity and fault conditions — useful for hot-swap sequencing where the host controller needs to verify the slot power before enabling the card bus. ## 160 mOhm Rds(on) and the 1A current ceiling The 160 mOhm maximum on-resistance per channel sets the conduction loss floor — at 1A load the dissipation is 160 mW per channel, which sums to 640 mW worst-case across all four outputs and must be accounted for in the 30-SSOP package's thermal budget. The 1A per-channel current limit is fixed and non-adjustable — designs drawing above 1A per slot will trip the current-limiting protection, so the TPS2202IDFR is sized for standard PCMCIA Type I/II cards, not high-power CardBus peripherals that may exceed this ceiling. The 30-SSOP package (0.209-inch body width, 5.30 mm height) and surface-mount footprint are standard for this family — any replacement candidate must match the same SSOP-30 land pattern and the 4.75V to 5.25V Vcc supply rail. ## Temperature grade and operating envelope The 4.75V to 5.25V Vcc supply rail powers the internal control logic and serial interface; the load-side voltages (3.3V, 5V, 12V) are supplied externally through the switch outputs.","metaTitle":"TPS2202IDFR PCMCIA Switch, Obsolete, Sourced to Order","metaDescription":"Texas Instruments TPS2202IDFR PCMCIA switch IC, 4-output high-side, 160mOhm max Rds(on), 1A per channel, 3.3V/5V/12V load.","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":"Power Good, Status Flag","Interface":"Serial","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":"$3.7500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fed7bed5e03f5bc3eca53670c02ae06d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2202IDFR/alternatives.json"},"ai":{"faq":[{"question":"Is TPS2202IDFR obsolete?","answer":"Yes, the TPS2202IDFR carries an Obsolete product status from Texas Instruments.
