The fixed current-limiting and over-temperature fault protection prevent the switch from exceeding its SOA during a card short or stalled fan. ## Obsolete — sourcing reality for sustainment programs ## Status flag output — what it signals to the host controller The Status Flag feature provides a digital open-drain output that asserts low when the switch enters current-limit or thermal-shutdown. The host PCMCIA controller reads this flag to initiate a card reset or power-cycle sequence. The serial interface configures which outputs are enabled and sets the fault-reporting mask.","metaTitle":"TPS2228PWPR PCMCIA Switch, 97mOhm, 4 Outputs, Obsolete","metaDescription":"Texas Instruments TPS2228PWPR PCMCIA power switch, 4 high-side outputs, 97mOhm Rds(on), 1A per channel, 1.8V/3.3V/5V load.","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":"Tape & Reel (TR)","Features":"Status Flag","Interface":"Serial","Input Type":"-","Output Type":"-","Switch Type":"PCMCIA Switch","Rds On (Typ)":"97mOhm","Mounting Type":"Surface Mount","Package / Case":"20-PowerTSSOP (0.173\\\", 4.40mm Width)","Product Status":"Obsolete","Voltage - Load":"1.8V, 3.3V, 5V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"4","Base Product Number":"TPS2228","Output Configuration":"High Side","Ratio - Input:Output":"3:4","Operating Temperature":"-40°C~85°C(TA)","Current - Output (Max)":"1A","Supplier Device Package":"20-HTSSOP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.4600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2d1bf787b22990ea5130c7cee83648d9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2228PWPR/alternatives.json"},"ai":{"faq":[{"question":"Is TPS2228PWPR obsolete?","answer":"Yes, the TPS2228PWPR carries an obsolete lifecycle status.
