It integrates four high-side outputs with a 3:4 input-to-output ratio, meaning three supply inputs are selectively routed to four output channels — the typical configuration for a dual-slot PCMCIA controller where each slot needs VCC and VPP rails. ## Fault protection and status reporting Fixed current limiting and over-temperature shutdown are built in — no external sense resistor or comparator needed. The Status Flag output (open-drain, active low) asserts when a fault condition is detected, which a host controller or PCMCIA bridge can poll to manage slot power-down sequencing. The serial interface controls output enable and VCC/VPP selection, reducing the GPIO count required from the host. Because Vcc/Vdd is not required for the switch's internal logic, the device powers up from the load supply rails directly — a detail that simplifies the power-up sequence in a multi-rail system.","metaTitle":"TPS2224ADB PCMCIA Power Switch, 95 mOhm, 4 Outputs, 24-SSOP","metaDescription":"Texas Instruments TPS2224ADB PCMCIA switch, 4 outputs, 95 mOhm typical Rds(on), 3.3V/5V/12V loads, -40°C to 85°C, active production.","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":"Serial","Input Type":"-","Output Type":"-","Switch Type":"PCMCIA Switch","Rds On (Typ)":"95mOhm","Mounting Type":"Surface Mount","Package / Case":"24-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":"TPS2224","Output Configuration":"High Side","Ratio - Input:Output":"3:4","Operating Temperature":"-40°C~85°C(TA)","Current - Output (Max)":"1A","Supplier Device Package":"24-SSOP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.8698","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/85b5b56277dd039b6836f3d0733598e6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2224ADB/alternatives.json"},"ai":{"faq":[{"question":"What is the typical Rds(on) for TPS2224ADB?","answer":"The typical Rds(on) is 95 mOhm per output. This value is measured at nominal load and 25°C; actual on-resistance will increase with junction temperature, so thermal design should account for the higher resistance at the 85°C end of the operating range."},{"question":"Is TPS2224ADB compatible with 3.3V and 5V loads?","answer":"Yes, the switch supports 3.3 V, 5 V, and 12 V load voltages. The 3:4 input-to-output ratio allows the three supply rails to be selectively routed to the four output channels, covering the VCC and VPP requirements of a standard PCMCIA or CardBus slot."},{"question":"Can TPS2224ADB replace TPS2224A?","answer":"The TPS2224ADB shares the same base product number (TPS2224) and is functionally equivalent to the TPS2224A variant. The 'DB' suffix indicates the 24-SSOP package and Tube shipping medium. Pin compatibility should be verified against the respective datasheets, but the base function and key ratings (4 outputs, 95 mOhm, 3.3V/5V/12V) are consistent across the family."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2224ADB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2224ADB when reusing this data.
