The 2.93V threshold is a good fit for 3.3V rails that need a brown-out detector set around 2.9V to catch supply droop before the downstream logic enters an undefined state. The base product number TPS3831 covers a family of threshold options.","metaTitle":"TI TPS3831K33DQNR Simple Reset IC, 2.93V Threshold","metaDescription":"Texas Instruments TPS3831K33DQNR simple reset/power-on reset IC with 2.93V threshold, active-low push-pull output, 120ms timeout. 4-X2SON (1x1mm) package.","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":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"120ms Minimum","Package / Case":"4-XDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3831","Voltage - Threshold":"2.93V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"4-X2SON (1x1)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/171738cafab7c3368a7e7902c6be9c34.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3831K33DQNR/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout for TPS3831K33DQNR?","answer":"The reset timeout is a minimum of 120ms.
