When VDD drops below 2.64V, the active-low open-drain output asserts reset and holds it for a minimum of 10 ms after the supply recovers. That 10 ms timeout is the minimum — actual timeout may be longer, so budget for the datasheet's full range in your watchdog or power-up sequencing. ## Automotive-grade and temperature range That puts it in the under-hood or engine-bay tier — not just cabin electronics. The open-drain output lets you wire-OR multiple reset signals on the same pull-up, common in safety-critical automotive designs. Supplied in an SOT-23-5 package. The 5-pin footprint is compact and the pinout is standard for this family: GND, RESET, VDD, MR (manual reset, not present on this variant), and NC.","metaTitle":"TPS3838L30QDBVRQ1 Simple Reset/Power-On Reset, AEC-Q100","metaDescription":"Texas Instruments TPS3838L30QDBVRQ1 is an automotive-grade simple reset/power-on reset IC with 2.64V threshold, active-low open-drain output, SOT-23-5 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"10ms Minimum","Package / Case":"SC-74A, SOT-753","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"TPS3838","Voltage - Threshold":"2.64V","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/68bd76a1a78d983ca3b9ca674d45cee5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3838L30QDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"Does TPS3838L30QDBVRQ1 have a direct replacement with the same package?","answer":"No direct replacement is listed by Texas Instruments for this exact order code. The TPS3838 family includes other threshold options (e.g., TPS3838L50 for 5V rails) in the same SOT-23-5 package, but those are also obsolete. For a pin-compatible alternative with the same threshold, you would need to evaluate a different supervisor family like the TPS382x series — but that requires a datasheet cross-check for pinout and timeout differences."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3838L30QDBVRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3838L30QDBVRQ1 when reusing this data.
