The output is active-low, open-drain, which means you can pull it up to any logic voltage (1.8V, 3.3V, 5V) independent of the monitored rail, or wire-OR it with other reset sources in multi-controller systems. The reset timeout is 120ms minimum — long enough for the supply to stabilise after a brown-out event, short enough that the system doesn't sit idle through a full power-up cycle. ## Automotive temp range and package reality The SOT-23-5 package (SC-74A, SOT-753 footprint) is a five-lead surface-mount package with 0.95mm pitch — easy to route on a two-layer board, no vias needed under the body.","metaTitle":"TPS3828-33QDBVRQ1 Simple Reset/Power-On Reset IC, AEC-Q100","metaDescription":"Texas Instruments TPS3828-33QDBVRQ1 is an automotive-grade (AEC-Q100) simple reset IC with a 2.93V threshold, active-low open-drain output, and 120ms minimum","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":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"120ms Minimum","Package / Case":"SC-74A, SOT-753","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3828","Voltage - Threshold":"2.93V","Operating Temperature":"-40°C~125°C(TA)","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/d068267aee9bf355c9a84c074b6f2f03.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3828-33QDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3828-33QDBVRQ1 automotive qualified?","answer":"Yes, the TPS3828-33QDBVRQ1 is part of the Automotive, AEC-Q100 series."},{"question":"What is the reset timeout of TPS3828-33QDBVRQ1?","answer":"The reset timeout is 120ms minimum. After the monitored voltage rises above the threshold, the reset output stays low for at least 120ms before releasing. This delay gives the supply rail and the system clock time to stabilise before the processor starts executing code."},{"question":"What is the difference between TPS3828-33QDBVRQ1 and TPS3828-33QDBVR?","answer":"The difference is the packaging and shipping medium.
