The 2.4V threshold suits monitoring a 2.5V or 3.3V rail where the supervisor must assert reset before the supply drops below the processor's minimum operating voltage. ## Temperature range and package — industrial and automotive fit Housed in a SOT-23-5 (SC-74A) package, the 5-pin footprint is a common supervisor layout — the open-drain output pulls to the pull-up rail, so the reset signal swings to the MCU's VDD regardless of the monitored rail voltage. ROHS3 compliant. ## Sourcing and quoting for volume The base product number TPS3840 covers multiple threshold options; the DL24 suffix locks the 2.4V threshold, so confirm the BOM calls for exactly that trip point.","metaTitle":"TPS3840DL24DBVR – TI Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3840DL24DBVR: Simple Reset/Power-On Reset IC, 2.4V threshold, active-low open-drain output, 619ms timeout, -40°C to 125°C, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"619ms Typical","Package / Case":"SC-74A, SOT-753","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3840","Voltage - Threshold":"2.4V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2100","priceTiers":[{"qty":1,"price":"$1.21000","currency":"USD"},{"qty":10,"price":"$1.08500","currency":"USD"},{"qty":25,"price":"$1.03000","currency":"USD"},{"qty":100,"price":"$0.84600","currency":"USD"},{"qty":250,"price":"$0.79080","currency":"USD"},{"qty":500,"price":"$0.69886","currency":"USD"},{"qty":1000,"price":"$0.55173","currency":"USD"},{"qty":3000,"price":"$0.39000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5c43cdc78d6ce4876119969a2f71b26e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3840DL24DBVR/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3840DL24DBVR an active low reset?","answer":"Yes, the reset output is active low.
