It integrates N-channel FETs internally. ## Supply range and output current — sizing the rail Rated for 2.8V to 5.5V input, the TPS2111PW works with Li-ion battery packs (3.0V–4.2V) as well as regulated 3.3V or 5V buses. The 1.25A maximum output is a continuous rating; if your load peaks above that, you need a higher-current part or a parallel path. At 55 µA supply current, the switch itself won't dominate the system power budget — compare that to the load current, and the overhead is negligible. ## Temperature grade and environment The 8-TSSOP package is surface-mount, so it reflows on a standard profile. No AEC-Q grade is listed, so it's not formally automotive-qualified, but the temperature range itself doesn't rule out benign under-hood use if you run your own qualification.","metaTitle":"TPS2111PW Source Selector Switch, 2.8V–5.5V, 1.25A, 8-TSSOP","metaDescription":"Texas Instruments TPS2111PW source selector switch: 2.8V–5.5V supply, 1.25A output, 55 µA quiescent, -40°C to 85°C, 8-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Type":"Source Selector Switch","Package":"Tube","FET Type":"N-Channel","Applications":"Handheld/Mobile Devices","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP (0.173\\\", 4.40mm Width)","Delay Time - ON":"1 ms","lifecycle_stage":"eol_hot","Current - Supply":"55 µA","Delay Time - OFF":"5 ms","Voltage - Supply":"2.8V ~ 5.5V","Internal Switch(s)":"Yes","Ratio - Input:Output":"2:1","Operating Temperature":"-40°C ~ 85°C","Current - Output (Max)":"1.25A","Supplier Device Package":"8-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.80000","currency":"USD"},{"qty":10,"price":"$2.51200","currency":"USD"},{"qty":25,"price":"$2.37480","currency":"USD"},{"qty":100,"price":"$2.05810","currency":"USD"},{"qty":250,"price":"$1.95260","currency":"USD"},{"qty":500,"price":"$1.75204","currency":"USD"},{"qty":1000,"price":"$1.47763","currency":"USD"},{"qty":2500,"price":"$1.40375","currency":"USD"},{"qty":5000,"price":"$1.35098","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b29f77f5270edff967d2a5f4518ab2a5.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2111PW","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2111PW when reusing this data.
