That active-low reset signal is what you feed into an MCU reset pin or a PLD enable — the open-drain topology lets you wire-OR it with other fault signals on the same pull-up. The SOT-23-6 Thin package keeps the footprint small enough for dense regulator layouts. ## Temperature range and package — bench-fit for industrial boards The SOT-23-6 Thin package (TSOT-23-6) is a surface-mount part with a low profile — the exposed pad helps pull heat into the board copper, though the part itself dissipates very little power. Surface-mount only; no through-hole variant. TI lists the TPS3702AX33DDCT as Active on the product status.","metaTitle":"Texas Instruments TPS3702AX33DDCT Voltage Detector","metaDescription":"Texas Instruments TPS3702AX33DDCT voltage detector with 3.3V threshold, active-low open-drain output, -40°C to 125°C range, SOT-23-6 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":"Voltage Detector","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"-","Package / Case":"SOT-23-6 Thin, TSOT-23-6","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3702","Voltage - Threshold":"3.3V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"SOT-23-THIN","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4254a8709547baa24f9ffd6bf45013c0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3702AX33DDCT/alternatives.json"},"ai":{"faq":[{"question":"Does TPS3702AX33DDCT have a watchdog timer?","answer":"No. The TPS3702AX33DDCT is a voltage detector with a single-channel reset output.
