It integrates a 4:1 input multiplexer (4:2 ratio) to select from 3.3 V, 5 V, or 12 V rails, with a typical on-resistance of 95 mOhm per channel at 1 A continuous output. ## Serial control and status flag for slot diagnostics A serial interface programs the output voltage selection and enables independent control of each channel. The status flag output reports fault conditions — current limiting or over-temperature — so the host controller can respond before the card loses power. ## Industrial temperature range, but obsolete — sourcing reality However, Texas Instruments has marked this device as obsolete. ## 24-HTSSOP package — thermal pad layout note The 0.65 mm pitch and 4.40 mm body width are standard for TSSOP-24, but the pad adds a thermal via requirement for high-current designs.","metaTitle":"Texas Instruments TPS2220BPWP PCMCIA Power Switch, 1A","metaDescription":"Texas Instruments TPS2220BPWP PCMCIA power switch, 2 outputs, 95mOhm Rds(on), 3.3V/5V/12V load, 24-HTSSOP.","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-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","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-HTSSOP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/64962a8fad7d321792fb2d9c1c36d09a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2220BPWP/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for TPS2220BPWP?","answer":"No official replacement or cross-reference is recorded for the TPS2220BPWP.
