That means you can drive the /RESET pin of a microcontroller with the active-low output while simultaneously feeding the active-high output to an FPGA's INIT_DONE or a power-good LED — no external inverter needed. The outputs are push-pull, so no pull-up resistor required on the active-low line. The SOT-23-5 package (SC-74A) is a five-pin footprint that fits on tight mixed-signal boards where every mm² counts. ## Industrial temperature range — field-ready The threshold voltage is trimmed at the factory and stays within ±1.5% over temperature, which is tighter than the resistor-divider-based supervisors you'd build from discrete comparators. Surface-mount only — the SOT-23-5 is a standard footprint for reflow assembly. No end-of-life notice, no last-time-buy deadline.","metaTitle":"TI TPS3824-33DBVR Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3824-33DBVR simple reset/power-on reset IC. 2.93V threshold, 120ms min timeout, active high/active low outputs.

That is the guaranteed time the part holds the reset outputs asserted after the supply rises above the threshold — long enough for most MCU oscillators and PLLs to lock before the processor starts executing code."},{"question":"Is TPS3824-33DBVR active high or active low reset?","answer":"Both. The TPS3824-33DBVR provides an active-high and an active-low reset output from the same IC. The active-low output (/RESET) drives the standard MCU reset pin; the active-high output can signal an FPGA, enable a power-good LED, or gate an external regulator's enable pin."},{"question":"What is the difference between TPS3824-33DBVR and TPS3824-50DBVR?","answer":"The only difference is the threshold voltage. The TPS3824-33DBVR monitors a 3.3 V rail with a 2.93 V threshold; the TPS3824-50DBVR monitors a 5 V rail with a 4.55 V threshold. They are pin-compatible, so swapping between them requires only a BOM change, not a board spin."},{"question":"What package does TPS3824-33DBVR come in?","answer":"It comes in a 5-pin SOT-23-5 package (also designated SC-74A). The supplier device package is SOT-23-5. It is surface-mount only, suitable for reflow soldering."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3824-33DBVR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3824-33DBVR when reusing this data.
