That means the output drives both high and low without requiring an external pull-up resistor, simplifying the board layout and reducing BOM count. ## SOT-23-3 package and surface-mount assembly Housed in a SOT-23-3 (TO-236-3, SC-59) package, this part is a straightforward surface-mount component for automated assembly. The three-pin footprint fits into compact designs where board space is tight.","metaTitle":"TPS3839K33DBZT Simple Reset/Power-On Reset, 2.93V Threshold","metaDescription":"Texas Instruments TPS3839K33DBZT simple reset/power-on reset IC, active-low push-pull output, 2.93V threshold, 120ms min reset timeout, SOT-23-3, -40°C to 85°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":"Push-Pull, Totem Pole","Series":"-","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"120ms Minimum","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3839","Voltage - Threshold":"2.93V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-3","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6ab752df07e5ba54cda63e55a487d606.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3839K33DBZT/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout for TPS3839K33DBZT?","answer":"The reset timeout is a minimum of 120 ms.
