The open-drain, active-low output lets you wire-OR the reset signal with other supervisors or pull it up to a different logic voltage. ## 10 ms timeout — debouncing the power-good signal That window is long enough for most MCU and DSP power-on sequences to complete their internal POR, but short enough that a system watchdog doesn't time out waiting for the processor to start. If your design needs a longer delay to sequence multiple rails, you'll need an external RC or a programmable supervisor. ## Industrial temperature range — where it fits The base product number TPS3838 covers a family of threshold options — if the 2.64V trip point doesn't match your rail, a different suffix in the same package and pinout may fit.","metaTitle":"TI TPS3838L30DBVTG4 Simple Reset IC, 2.64V Threshold","metaDescription":"Texas Instruments TPS3838L30DBVTG4 simple reset/power-on reset IC with active-low open-drain output. 2.64V threshold, 10ms timeout, -40°C to 85°C.","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":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Reset Timeout":"10ms Minimum","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Base Product Number":"TPS3838","Voltage - Threshold":"2.64V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/020841d6578f782f4748e70ad552a6db.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3838L30DBVTG4/alternatives.json"},"ai":{"faq":[{"question":"What is the exact reset threshold voltage of TPS3838L30DBVTG4?","answer":"The reset threshold voltage is 2.64V, which is the voltage at which the output asserts a reset when the monitored supply falls below that level."},{"question":"Does TPS3838L30DBVTG4 have an active low or open drain output?","answer":"The output is active low and open drain — it pulls low when the supply drops below the threshold, and requires an external pull-up resistor to a logic voltage to define the high state."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3838L30DBVTG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3838L30DBVTG4 when reusing this data.
