Its N-channel FETs deliver up to 1.25 A continuous from whichever input is selected, with a typical on-resistance that stays under 100 mΩ at 3.3 V — the exact value depends on the supply voltage and temperature, but the headline here is that the pass element burns far less power than a diode at the same current. ## Supply range and quiescent current Quiescent supply current is 55 µA typical — low enough that the mux does not drain the battery when the system is idle, but not a sub-microamp figure; if the design sleeps at single-digit microamps, the TPS2115PWR's own draw needs to be gated or the part placed after the load switch. ## Switching timing and the 2:1 ratio The 2:1 input-to-output ratio means one of two supply inputs is routed to the single output. The delay times — 1 ms on, 5 ms off — are set by internal timing and cannot be adjusted externally. For a handheld device that hot-swaps between USB and battery, the 5 ms off delay prevents the output from glitching during the transition; the 1 ms on delay gives the incoming supply time to settle before the switch closes. That means no forced redesign for obsolescence on this BOM line.","metaTitle":"Texas Instruments TPS2115PWR Source Selector Switch, 1.25A","metaDescription":"Active-production TI TPS2115PWR source selector switch, N-channel, 2:1 mux, 1.25A max output, 55 µA supply, -40°C to 85°C, 8-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Source Selector Switch","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","FET Type":"N-Channel","Applications":"Handheld/Mobile Devices","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","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","Base Product Number":"TPS2115","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":"$2.7200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/225cdf542d580a311f0954af594ee0ea.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2115PWR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2115PWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2115PWR when reusing this data.
