The reset output is active-low, push-pull, and totem-pole — no external pull-up resistor is needed on the output pin, which saves a component and a board trace in tight layouts. ## 2.8V threshold and 20 ms reset timeout for glitch rejection The 2.8V threshold monitors a single supply rail — a common choice for supervising a 3.3V or 3.0V core supply, asserting reset before the rail drops below the processor's minimum operating voltage. The minimum reset timeout of 20 ms filters out short supply transients that could otherwise cause false resets — a 20 ms window is long enough to ride through a load-step dip on a properly decoupled rail but short enough to hold the system in reset through a brown-out event. Monitors exactly one voltage, so the BOM carries one supervisor per supervised rail; a multi-rail system uses multiple instances of this part or a multi-channel supervisor. ## SC-70-3 package for space-constrained boards Surface-mount assembly with the standard SC-70 land pattern — no thermal pad or exposed paddle, so the solder profile follows the standard JEDEC reflow for small-outline packages.","metaTitle":"MAX6381XR28D2+ Power Supply Monitor, 2.8V Threshold, SC-70-3","metaDescription":"MAX6381XR28D2+ Analog Devices single-voltage supervisor, 2.8V threshold, active-low reset, push-pull output, -40°C to +125°C, AEC-Q100, SC-70-3.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Power Supply Monitor","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Series":"Automotive, AEC-Q100","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"20ms Minimum","Package / Case":"SC-70, SOT-323","lifecycle_stage":"eol_hot","Voltage - Threshold":"2.8V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SC-70-3","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/2a43ef6f52c719a0bf0ab10173c69901.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What does the 2.8V threshold mean for my circuit?","answer":"The 2.8V threshold is the falling-voltage trip point at which the active-low reset output asserts. For a 3.3V supply rail, this threshold sits roughly 15% below nominal — early enough to hold the processor in reset before the rail drops below its minimum operating voltage, but not so early that normal load transients cause false resets."},{"question":"Does the MAX6381XR28D2+ require an external pull-up on the reset output?","answer":"No. The reset output is push-pull, totem pole, meaning it actively drives both high and low.
