The output is active-low push-pull, which means it pulls the reset line low during a fault and drives it high again once the supply is stable and the 20ms minimum timeout expires. This part is designed for surface-mount assembly in the compact SC-70-4 package, making it a fit for space-constrained boards in industrial control, telecom, and embedded systems where a reliable power-on reset is needed. ## Temperature range and operating environment Rated for -40°C to 85°C ambient, the MAX6838XSD2+T covers the industrial temperature grade. That spans factory-floor enclosures, outdoor telecom cabinets, and engine-bay-adjacent electronics where the board sees thermal cycling but not the full military range. The SC-70-4 package is small enough to fit on a cramped PCB alongside an MCU or FPGA that needs a clean reset signal at power-up. ## Lifecycle and sourcing posture The MAX6838XSD2+T carries an active lifecycle status and is ROHS3 compliant. There is no end-of-life notice or last-time-buy window to manage. For BOM planning, this part is available through independent distribution and is sourced to order against an RFQ.","metaTitle":"MAX6838XSD2+T Simple Reset/Power-On Reset IC, SC-70-4","metaDescription":"MAX6838XSD2+T from Maxim Integrated: Simple Reset/Power-On Reset, Active Low, Push-Pull output, 20ms min timeout, -40°C to 85°C, SC-70-4.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Package":"Strip","Mounting Type":"Surface Mount","Reset Timeout":"20ms Minimum","Package / Case":"SC-82A, SOT-343","lifecycle_stage":"eol_hot","Voltage - Threshold":"Adjustable/Selectable","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SC-70-4","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.71","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.71000","currency":"USD"},{"qty":10,"price":"$3.11400","currency":"USD"},{"qty":25,"price":"$2.91600","currency":"USD"},{"qty":100,"price":"$2.61000","currency":"USD"},{"qty":250,"price":"$2.43000","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/max6832-max6840.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reset timeout of the MAX6838XSD2+T?","answer":"The reset timeout is 20ms minimum. This means the reset output stays low for at least 20ms after the monitored voltage rises above the threshold, giving the system time to stabilize before the processor starts executing code."},{"question":"Is MAX6838XSD2+T compatible with 3.3V systems?","answer":"The voltage threshold is adjustable/selectable, so the part can be configured for 3.3V or other common rail voltages by choosing the appropriate threshold variant in the MAX6838 family. The MAX6838XSD2+T itself has a factory-set threshold; verify the specific threshold code against your supply rail."},{"question":"What is the difference between MAX6838XSD2+T and MAX6838XSD1+T?","answer":"The difference is the factory-programmed voltage threshold. The MAX6838XSD2+T and MAX6838XSD1+T are the same die and package, but each has a different threshold voltage selected at the factory. Check the threshold codes in the datasheet to match your supply rail."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6838XSD2T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6838XSD2T when reusing this data.
