It is specified for handheld and mobile devices where a battery and a USB or adapter supply share the same load bus. ## Current and voltage envelope for the BOM Rated for a continuous output current of 1.25 A maximum, the TPS2115APWRG4 fits loads such as a sensor node radio, a small microcontroller, or a peripheral bus that draws under that ceiling. Quiescent supply current is 55 µA typical — low enough that the switch does not dominate the standby budget in a battery-powered product. ## Switching timing and temperature grade Turn-on delay is 1 ms and turn-off delay is 5 ms. These numbers matter for sequencing: the output rail ramps after the 1 ms delay, so the downstream load must tolerate that startup latency. The 5 ms off delay means the switch holds the output for 5 ms after the selected input drops — enough to ride through a brief supply glitch without toggling the load.","metaTitle":"TPS2115APWRG4 Source Selector Switch, 1.25 A, 8-TSSOP","metaDescription":"Texas Instruments TPS2115APWRG4 source selector switch, 2:1 input mux, 1.25 A output, 2.8 V to 5.5 V 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)","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","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/113c7e6abfa471d18b79d146b97418ef.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2115APWRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS2115A and TPS2115APWRG4?","answer":"The TPS2115APWRG4 is the Tape & Reel packaged variant of the base TPS2115A device.
