This gives the oscillator and internal regulator of the supervised processor time to stabilise before the first instruction fetch. In a system with a slow-start supply or a large bulk capacitor, the timeout ensures the processor does not start until the rail is solid. ## Dual complementary reset outputs The TPS3824-25DBVT provides both active-high and active-low reset outputs in a push-pull, totem-pole configuration. No external pull-up resistor is needed on the active-low output — it drives high when reset is de-asserted. This simplifies the BOM for processors that require either polarity, and the push-pull output eliminates the pull-up resistor that a standard open-drain reset would need. ## Industrial temperature range, SOT-23-5 package The SOT-23-5 package (SC-74A, SOT-753) is a standard five-pin surface-mount footprint, 0.95 mm pitch, easy to route on a two-layer board. The supplier device package is SOT-23-5, which is the same mechanical outline as the SC-74A. The base product number is TPS3824, and the -25 suffix denotes the 2.25V threshold variant. For a 3.3V system, this is the correct threshold — the -33 variant (TPS3824-33DBVT) monitors for a 3.07V threshold, which is tighter to the rail.","metaTitle":"TI TPS3824-25DBVT Simple Reset/Power-On Reset IC","metaDescription":"Texas Instruments TPS3824-25DBVT simple reset/power-on reset IC with 2.25V threshold, 120ms min timeout, active high/low outputs, industrial temp range.","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 High/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":"SC-74A, SOT-753","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3824","Voltage - Threshold":"2.25V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fa41d36737292d75f54b3a8afbef0279.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3824-25DBVT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3824-25DBVT suitable for 3.3V systems?","answer":"Yes. The threshold is 2.25V, which is below the minimum operating voltage of most 3.3V processors (typically 3.0V to 3.6V). The reset asserts when the rail drops to 2.25V, well before the processor's brown-out threshold, giving the core time to shut down cleanly. For a tighter threshold closer to 3.3V, the TPS3824-33DBVT (3.07V threshold) is the alternative."},{"question":"Can TPS3824-25DBVT be used as replacement for TPS3824-33DBVT?","answer":"Not without verifying the threshold. The TPS3824-25DBVT has a 2.25V threshold, while the TPS3824-33DBVT has a 3.07V threshold. In a 3.3V system, the -33 variant asserts reset closer to the rail, which may be needed if the processor requires a tighter supervision window. The pinout and package are identical, so a board swap is possible if the threshold difference is acceptable."},{"question":"What is the reset timeout of TPS3824-25DBVT?","answer":"The reset timeout is 120 ms minimum. After the supply rises above the 2.25V threshold, the reset output remains asserted for at least 120 ms before releasing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3824-25DBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3824-25DBVT when reusing this data.
