It accepts load voltages of 3.3 V, 5 V, and 12 V, with each output rated for a maximum of 1 A continuous current. The switch integrates fixed current limiting and over-temperature protection to guard against card faults and hot-plug transients. ## 95 mOhm on-resistance and thermal budget Typical on-resistance of 95 mOhm sets the conduction loss at 95 mW per amp per output at 25 °C. In a three-output slot drawing 1 A on VCC and 100 mA on each VPP rail, total dissipation sits around 115 mW — well within the SSOP-24 package capability at 85 °C ambient, but the fixed current-limit threshold must be checked against the card inrush profile. ## Serial interface and status flag Control is via a serial interface, which reduces host GPIO count compared to parallel-controlled switches. The status flag output reports over-current or over-temperature faults, allowing the system controller to sequence a card reset or power-down. The 24-SSOP package (0.209-inch body width, 5.30 mm) requires a standard SSOP-24 land pattern; the 0.65 mm pitch is manageable on two-layer boards with careful fan-out. ## Sourcing an obsolete PCMCIA switch No official successor or second-source alternate is recorded. Confirm the BOM quantity and any date-code requirements before committing.","metaTitle":"TPS2220ADBG4 PCMCIA Power Switch, 95mOhm, Obsolete","metaDescription":"Texas Instruments TPS2220ADBG4 PCMCIA switch, 3 outputs, 1A, 95mOhm, 3.3V/5V/12V, SSOP-24.","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":"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":"Obsolete","Voltage - Load":"3.3V, 5V, 12V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"3","Base Product Number":"TPS222","Output Configuration":"High Side","Ratio - Input:Output":"1:1","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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/37710a5e5fc400087cbcb1c1c78ae6f7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2220ADBG4/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy TPS2220ADBG4?","answer":"The TPS2220ADBG4 is obsolete and no longer in production."},{"question":"What is the replacement for TPS2220ADBG4?","answer":"No official replacement or cross-reference is recorded for the TPS2220ADBG4.
