Listed as Active on the product status. The base product number TPS389050 covers a family of threshold-voltage variants, so supply continuity for the 5V version tracks the broader family's production commitment.","metaTitle":"TPS389050LQDSERQ1 Simple Reset IC, 5V Threshold, AEC-Q100","metaDescription":"Texas Instruments TPS389050LQDSERQ1 is an automotive AEC-Q100 simple reset/power-on reset IC with a 5V threshold, active-low open-drain output, -40°C to 125°C","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"Automotive, AEC-Q100","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"-","Package / Case":"6-WFDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS389050","Voltage - Threshold":"5V","Operating Temperature":"-40°C ~ 125°C (TJ)","Supplier Device Package":"6-WSON (1.5x1.5)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b45b0104a3f5ff10693a4ea91fba4703.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS389050LQDSERQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS389050LQDSERQ1 AEC-Q100 qualified for automotive use?","answer":"Yes, the series is listed as Automotive, AEC-Q100.
