The switch integrates current limiting and over-temperature fault protection, and includes a status flag output for fault reporting. ## 97 mOhm Rds(on) — thermal budget for the slot With a typical on-resistance of 97 mOhm per output, the TPS2221PWPG4 dissipates about 97 mW at the 1 A maximum continuous current. ## 14-HTSSOP package — layout notes The pad must be connected to the ground plane with multiple vias under the package for effective heat spreading. The parallel interface uses a 3:2 input-to-output ratio — three control lines manage two outputs.","metaTitle":"TPS2221PWPG4 PCMCIA Power Switch, 97mOhm","metaDescription":"Texas Instruments TPS2221PWPG4 dual high-side PCMCIA switch, 1A per output, 97mOhm Rds(on), 14-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":"Parallel","Input Type":"-","Output Type":"-","Switch Type":"PCMCIA Switch","Rds On (Typ)":"97mOhm","Mounting Type":"Surface Mount","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","Product Status":"Obsolete","Voltage - Load":"1.8V, 3.3V, 5V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"2","Base Product Number":"TPS2221","Output Configuration":"High Side","Ratio - Input:Output":"3:2","Operating Temperature":"-40°C~85°C(TA)","Current - Output (Max)":"1A","Supplier Device Package":"14-HTSSOP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2d1bf787b22990ea5130c7cee83648d9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2221PWPG4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for TPS2221PWPG4?","answer":"Texas Instruments has not designated an official successor for the TPS2221PWPG4.
