The switch is controlled via a serial interface and provides a status flag output to the host controller for fault reporting. No external Vcc/Vdd supply is required for the control logic — the switch is self-powered from the load rail. ## Package and temperature grade — 30-SSOP, industrial range The supplier device package is 30-SSOP. ## Lifecycle status — obsolete, no direct replacement listed The TPS2228DB is classified as obsolete by the manufacturer. No official successor or cross-reference part number is recorded in the lifecycle data.","metaTitle":"TPS2228DB PCMCIA Power Switch, 97 mOhm, 30-SSOP","metaDescription":"Texas Instruments TPS2228DB quad high-side PCMCIA switch, 1 A per output, 97 mOhm typ Rds(on), 30-SSOP.","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)":"97mOhm","Mounting Type":"Surface Mount","Package / Case":"30-SSOP (0.209\\\", 5.30mm 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":"TPS222","Output Configuration":"High Side","Ratio - Input:Output":"3:4","Operating Temperature":"-40°C~85°C(TA)","Current - Output (Max)":"1A","Supplier Device Package":"30-SSOP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.3600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2d1bf787b22990ea5130c7cee83648d9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2228DB/alternatives.json"},"ai":{"faq":[{"question":"Is the TPS2228DB obsolete and what is the replacement?","answer":"Yes, the TPS2228DB is listed as obsolete.
