Its 160 mOhm max Rds(on) per output at 1 A continuous current defines the voltage drop and power dissipation the board must handle. The serial interface controls the output configuration, and the 3:4 input-to-output ratio lets three supply rails feed four independent switch channels. Built-in fault protection includes fixed current limiting and over-temperature shutdown, so a shorted card slot or stalled fan on the host controller won't cascade into a board-level failure. The power-good and status-flag outputs give the host controller visibility into each slot's health without polling the serial bus. Production has ended, and new stock is no longer manufactured. Sourcing is limited to independent distribution — surplus inventory, factory overruns, and broker-held stock. ## Package and footprint — 30-SSOP with 0.65 mm pitch ## Supply rails and control interface The serial interface programs which output connects to which rail, and the 3:4 input-to-output ratio means one rail can feed multiple outputs, but not all four simultaneously if each needs a different voltage.","metaTitle":"TPS2202AIDB PCMCIA Power Switch, 160mOhm, 30-SSOP","metaDescription":"Texas Instruments TPS2202AIDB PCMCIA switch IC, 4 outputs, 1A max, 160mOhm Rds(on), 30-SSOP.","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":"Tube","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":"$7.1200","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2202AIDB/alternatives.json"},"ai":{"faq":[{"question":"What is the Rds(on) of TPS2202AIDB?","answer":"The maximum Rds(on) is 160 mOhm per output at the rated 1 A continuous current.
