It is designed for PCMCIA and CardBus slots where the host controller sequences VCC and VPP to the card — the 3:4 input-to-output ratio means three serial bits control four outputs, one of which is typically the VPP programming voltage. Each output is rated for 1 A continuous with a typical on-resistance of 95 mOhm. ## Fault protection and status reporting Built-in fault protection includes fixed current limiting and overtemperature shutdown — no external sense resistor or comparator needed. The status flag output (open-drain, active low) asserts when a fault condition is detected, giving the host controller a direct interrupt signal. The output configuration is high-side, meaning the switch sits between the supply rail and the load. Because the device does not require a Vcc/Vdd bias supply — the gate drive is derived from the load voltage itself — it simplifies the power tree for space-constrained PCMCIA implementations. The 24-SSOP package (5.30 mm body width, 0.209-inch pitch) is a surface-mount footprint compatible with standard reflow profiles.","metaTitle":"TPS2223ADBG4 PCMCIA Power Switch, 95 mOhm, 4 Outputs","metaDescription":"Texas Instruments TPS2223ADBG4 PCMCIA switch IC. 4 high-side outputs, 95 mOhm typ Rds(on), 3.3V/5V load, serial interface, status flag, -40 to 85°C.","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)","Voltage - Load":"3.3V, 5V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"4","Base Product Number":"TPS2223","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":"$3.2200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/85b5b56277dd039b6836f3d0733598e6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2223ADBG4/alternatives.json"},"ai":{"faq":[{"question":"What is TPS2223ADBG4 used for?","answer":"Typical applications include notebook docking stations, industrial PCMCIA data-acquisition modules, and telecom line cards with CardBus slots."},{"question":"How many outputs does TPS2223ADBG4 have?","answer":"Four high-side outputs, controlled by three serial interface inputs (3:4 ratio).
