The reset output remains low for a minimum of 1 ms after all monitored voltages return above threshold, providing a clean power-on reset signal for microcontrollers, DSPs, or FPGAs that need a guaranteed hold time before the core starts executing code. Housed in a 4-lead SC-70 (SOT-343) package, the footprint matches the standard SC-70-4 land pattern — the same pad geometry used by many single- and dual-voltage supervisors, so a board spin is not required when swapping between similar parts from the same family.","metaTitle":"MAX6389XS33D1 Multi-Voltage Supervisor, SC-70-4","metaDescription":"MAX6389XS33D1 multi-voltage supervisor from Analog Devices, monitors 2 voltages, active-low open-drain reset, 1ms min timeout, SC-70-4, -40 to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Type":"Multi-Voltage Supervisor","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"1ms Minimum","Package / Case":"SC-82A, SOT-343","lifecycle_stage":"eol_hot","Voltage - Threshold":"3.3V, Adj","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SC-70-4","Number of Voltages Monitored":"2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.74","stockQuantity":0,"priceTiers":[{"qty":110,"price":"$2.74000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2a43ef6f52c719a0bf0ab10173c69901.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reset timeout for MAX6389XS33D1?","answer":"The reset timeout is a minimum of 1 ms — the reset output stays low for at least 1 ms after all monitored voltages rise above their thresholds, giving the downstream processor time to stabilize before releasing the reset line."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6389XS33D1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6389XS33D1 when reusing this data.
