Each output is rated for 500 mA continuous with a typical on-resistance of 80 mOhm, making it suited for distributing power to USB peripherals, logic loads, or general-purpose board-level switched rails. The switch is enabled by a logic-level On/Off interface with a non-inverting input; no external Vcc supply is needed because the gate drive is derived from the load voltage itself. Built-in fault protection includes fixed current limiting, over-temperature shutdown, and undervoltage lockout (UVLO). A status flag output reports overcurrent or overtemperature conditions, which can be tied to a host controller interrupt or a diagnostic LED. The switch operates over a load supply range of 2.7 V to 5.5 V and a junction temperature range of 0°C to 125°C, covering most commercial and industrial environments. ## What the 80 mOhm Rds(on) and 500 mA rating mean for the BOM The fixed current limit is not adjustable. ## Package and footprint — 8-SOIC The TPS2081D comes in the standard 8-SOIC package (3.90 mm body width), which is a common footprint for board-level power switches. The surface-mount package suits automated assembly and reflow soldering. The tube shipping medium is typical for prototype and low-volume builds; for production volumes, the part is also available in tape-and-reel (check the reel suffix when ordering). ## Lifecycle and sourcing No last-time-buy or obsolescence notice is in effect, so the part is suitable for new designs and production ramps. It is ROHS3 compliant.","metaTitle":"TPS2081D Power Switch, 2-Channel High-Side, 500mA, 8-SOIC","metaDescription":"TI TPS2081D dual high-side power switch, 80mOhm Rds(on), 500mA per output, 2.7-5.5V, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Features":"Status Flag","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"80mOhm","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Voltage - Load":"2.7V ~ 5.5V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature, UVLO","Number of Outputs":"2","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"0°C ~ 125°C (TJ)","Current - Output (Max)":"500mA","Supplier Device Package":"8-SOIC","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.25","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.25000","currency":"USD"},{"qty":10,"price":"$2.02000","currency":"USD"},{"qty":25,"price":"$1.90520","currency":"USD"},{"qty":100,"price":"$1.62340","currency":"USD"},{"qty":250,"price":"$1.52428","currency":"USD"},{"qty":500,"price":"$1.33374","currency":"USD"},{"qty":1000,"price":"$1.10510","currency":"USD"},{"qty":2500,"price":"$1.07850","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e764d3522d5d4eb14351cfb18e57bbd9.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can TPS2081D be used as a high-side switch?","answer":"Yes, the TPS2081D is configured as a dual high-side N-channel switch. Each output switches the load supply voltage to the load, with the internal charge pump generating the gate drive from the load voltage itself."},{"question":"What is the difference between TPS2081D and TPS2080D?","answer":"The TPS2081D and TPS2080D are both dual high-side switches in the same family. The primary difference is the current limit threshold: the TPS2081D is rated for 500 mA per output, while the TPS2080D is rated for a lower current (typically 250 mA per output). Pinout and package are identical, so they are drop-in replacements if the load current fits the lower limit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2081D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2081D when reusing this data.
