It places cleanly on a two-layer board with no via-in-pad requirement. The MSL rating for this package family is typically Level 1 (260°C reflow, unlimited floor life), so no pre-bake is needed before the reflow oven — it survives the profile without popcorning.","metaTitle":"Texas Instruments TPS22918TDBVTQ1 Load Switch, 52 mOhm","metaDescription":"Texas Instruments TPS22918TDBVTQ1 automotive load switch, 52 mOhm Rds(on), 2 A max, SOT-23-6, -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":"$1.3300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a134eeadd74a3568fc68398e908d531e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS22918TDBVTQ1/alternatives.json"},"ai":{"faq":[{"question":"What is the Rds(on) of TPS22918TDBVTQ1?","answer":"The typical on-resistance is 52 mOhm at 5 V bias and 25°C junction temperature. This value increases with temperature per the normalised curve in the datasheet; at 105°C junction the Rds(on) roughly doubles, so budget 100 mOhm for worst-case conduction loss at high ambient."},{"question":"Is TPS22918TDBVTQ1 AEC-Q100 qualified?","answer":"Yes, the part is listed under the Automotive, AEC-Q100 series.
