It distributes the three standard PCMCIA supply voltages — 3.3 V, 5 V, and 12 V — to the card slot with a 3:4 input-to-output ratio, meaning three input rails feed four switched outputs. Each output is rated for 1 A continuous, with a typical on-resistance of 103 mOhm. The switch operates without a Vcc supply pin — the load voltage itself powers the internal charge pump. Built-in fault protection includes fixed current limiting and over-temperature shutdown, eliminating the need for external sense resistors or comparators. A status flag output reports over-current or thermal fault conditions to the host controller. ## Parallel interface and status flag — BOM simplification The parallel control interface directly maps logic inputs to output enable states, so no serial protocol or external latch is needed. The status flag is an open-drain output that pulls low during a fault — it can be wired-ORed with other fault signals on the board. Because the switch handles 12 V for VPP programming, the 103 mOhm Rds(on) at that rail keeps voltage drop under 100 mV at 1 A, which stays within the PCMCIA specification for programming voltage tolerance. ## 30-SSOP package and temperature grade The TPS2205IDBR is supplied in a 30-SSOP package with 0.209-inch body width and 5.30 mm height, surface-mount. The base product number is TPS2205, so the IDBR variant shares the same die and electrical characteristics as the TPS2205 family.","metaTitle":"TPS2205IDBR PCMCIA Switch, 4-Channel High-Side, 103 mOhm","metaDescription":"Texas Instruments TPS2205IDBR PCMCIA switch array, 4 high-side outputs, 103 mOhm typical Rds(on), 1 A per channel, 3.3V/5V/12V loads.","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":"Tape & Reel (TR); Cut Tape (CT)","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":"$4.0260","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ec947e78298ef43443a0a9084f1076cd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2205IDBR/alternatives.json"},"ai":{"faq":[{"question":"What is the typical Rds(on) of TPS2205IDBR?","answer":"The typical on-resistance is 103 mOhm per output channel.
