It integrates two 1 A rated outputs with a 4:2 input-to-output ratio, meaning four supply inputs (3.3 V, 5 V, 12 V) are routed to two switched outputs under serial interface control. The 95 mOhm typical Rds(on) keeps conduction loss low at the 1 A per-channel ceiling. ## 95 mOhm Rds(on) and the thermal budget At 1 A output, the 95 mOhm typical on-resistance drops about 95 mV and dissipates 95 mW per channel. ## Fault protection and the status flag Fixed current limiting and over-temperature shutdown protect the switch and the card slot from shorts or overcurrent events. The status flag output (open-drain, active low) signals a fault condition to the host controller — useful for hot-plug sequencing where the system needs to retry or log the event. The TPS2220BDB is officially obsolete per Texas Instruments. No successor or direct replacement order code is listed on the lifecycle record.","metaTitle":"TPS2220BDB PCMCIA Power Switch, 95 mOhm, Obsolete","metaDescription":"Texas Instruments TPS2220BDB dual-output PCMCIA switch, 95 mOhm typ Rds(on), 3.3V/5V/12V load, -40°C to 85°C.","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":"2","Base Product Number":"TPS222","Output Configuration":"High Side","Ratio - Input:Output":"4:2","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":"$0.9400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/64962a8fad7d321792fb2d9c1c36d09a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2220BDB/alternatives.json"},"ai":{"faq":[{"question":"Is TPS2220BDB obsolete?","answer":"Yes, Texas Instruments lists the TPS2220BDB as obsolete."},{"question":"What is the replacement for TPS2220BDB?","answer":"No official replacement or pin-compatible alternate is listed by Texas Instruments.
