It integrates three independent outputs — one for VCC and two for VPP — each capable of delivering up to 1A continuous. The switch handles the three standard PCMCIA supply rails (3.3V, 5V, and 12V) and is controlled via a serial interface. A status flag output reports fault conditions, and built-in fixed current limiting plus over-temperature shutdown protect both the host and the card from overcurrent events. The 95 mOhm typical Rds(on) sets the conduction loss floor: at 1A per output, each channel dissipates roughly 95 mW in the switch, which sums to under 300 mW for all three outputs — manageable in the 24-SSOP package without airflow, but the board copper area under the package matters for thermal spreading. The 1:1 input-to-output ratio means each output is independently gated by the serial interface — there is no sequencing logic on-chip; the host controller must manage the power-up and power-down sequence per the PCMCIA specification. Fault protection is fixed — the current limit threshold is not adjustable, and the over-temperature shutdown is non-latching (auto-retry). If the application needs a latched shutdown or an adjustable current limit, a different switch family is required.","metaTitle":"TPS2220ADB PCMCIA Power Switch, 95 mOhm, 3 Outputs, 24-SSOP","metaDescription":"Texas Instruments TPS2220ADB PCMCIA switch IC, 3 high-side outputs, 1A each, 95 mOhm Rds(on), 24-SSOP, obsolete.","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":"$1.2600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/37710a5e5fc400087cbcb1c1c78ae6f7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2220ADB/alternatives.json"},"ai":{"faq":[{"question":"Is the TPS2220ADB obsolete?","answer":"Yes, the TPS2220ADB has an obsolete lifecycle status.
