Its active-low, open-drain output lets it interface directly with microcontroller reset inputs or other logic without level-shifting. The adjustable/selectable threshold gives flexibility to set the trip point for different supply voltages. With an operating temperature range of -40°C to 125°C, it is suited for industrial and automotive environments where the board sees wide thermal swings — engine bays, outdoor telecom cabinets, or factory-floor controllers. ## Package and mounting Housed in a SOT-23-8 surface-mount package, the MAX6749KA fits on compact PCBs where board area is tight. The supplier device package is also SOT-23-8, so footprint and land pattern are standard. Surface-mount assembly is typical for reflow soldering; no special handling beyond normal SMD practice. ## Lifecycle and sourcing That means it remains available for new designs and production builds without last-time-buy risk. Note that the part is RoHS non-compliant, so verify your assembly's RoHS exemption requirements before specifying it for lead-free processes.","metaTitle":"MAX6749KA Simple Reset/Power-On Reset IC, SOT-23-8","metaDescription":"MAX6749KA is a simple reset/power-on reset IC with active-low open-drain output, 5.692ms min reset timeout, SOT-23-8 package, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"5.692ms Minimum","Package / Case":"SOT-23-8","lifecycle_stage":"eol_hot","Voltage - Threshold":"Adjustable/Selectable","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-23-8","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.74","stockQuantity":0,"priceTiers":[{"qty":110,"price":"$2.74000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e4956ac798fdbd360767041eac708c9a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reset timeout of MAX6749KA?","answer":"The reset timeout is 5.692ms minimum. This is the duration the reset output stays low after the monitored supply rises above the threshold, ensuring the system stabilises before the processor starts."},{"question":"Can MAX6749KA be used with 3.3V logic?","answer":"Yes, because the voltage threshold is adjustable/selectable, the trip point can be set for 3.3V rails.
