Its 52 mOhm typical on-resistance keeps conduction losses low enough that the SOT-23-6 package can handle the current without excessive heating at 85°C ambient. ## Rds(on) and thermal budget at 2 A At 2 A continuous, the 52 mOhm typical Rds(on) dissipates about 208 mW — well within the SOT-23-6's thermal capability at 105°C junction, but board copper area matters. The load discharge feature pulls the output low when the switch is off, preventing floating rails on capacitive loads.","metaTitle":"TPS22918TDBVRQ1 Automotive Load Switch, 52 mOhm, SOT-23-6","metaDescription":"AEC-Q100 qualified load switch, 52 mOhm Rds(on), 2 A output, 1 V to 5.5 V range, -40°C to 105°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Load Discharge, Slew Rate Controlled","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"52mOhm","Mounting Type":"Surface Mount","Package / Case":"SOT-23-6","Product Status":"Active","Voltage - Load":"1V ~ 5.5V","lifecycle_stage":"eol_hot","Fault Protection":"-","Number of Outputs":"1","Base Product Number":"TPS22918","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~105°C(TA)","Current - Output (Max)":"2A","Supplier Device Package":"SOT-23-6","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a134eeadd74a3568fc68398e908d531e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS22918TDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"Does TPS22918TDBVRQ1 support load discharge?","answer":"Yes, the part includes a load discharge feature that actively pulls the output to ground when the switch is off, preventing the output from floating on capacitive loads."},{"question":"Is TPS22918TDBVRQ1 AEC-Q100 qualified?","answer":"Yes, it is listed under the Automotive, AEC-Q100 series, qualified for automotive-grade applications."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS22918TDBVRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS22918TDBVRQ1 when reusing this data.
