This threshold is set for a nominal 3.3V rail, providing a brown-out detection window that catches supply dips before the downstream logic enters an undefined state. The active-low, push-pull output drives the reset line directly without needing an external pull-up resistor. ## AEC-Q100 grade for under-hood deployment The 15ms minimum reset timeout gives the power supply and oscillator time to stabilise before the processor boots — a margin that matters in cold-crank and load-dump transients. ## SOT-23-5 footprint and supply chain Housed in a 5-pin SOT-23-5 package (SC-74A, SOT-753), this part shares the same footprint as many other TI voltage supervisors, easing board-level substitution.","metaTitle":"TPS3820-33QPDBVRQ1 Automotive Voltage Monitor","metaDescription":"Texas Instruments TPS3820-33QPDBVRQ1 voltage monitor with 2.93V threshold, active-low push-pull output, 15ms reset timeout.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Monitor","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"15ms Minimum","Package / Case":"SC-74A, SOT-753","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3820","Voltage - Threshold":"2.93V","Operating Temperature":"-40°C~125°C","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4827b9b8bc7d46d2e7b061fade28aec5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3820-33QPDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS3820-33QPDBVRQ1 and TPS3820-33QDBVRQ1?","answer":"The suffix difference (QPDBVR vs QDBVR) typically indicates packaging or reel quantity variations within the same base device.
