The open-drain output pulls low on a fault condition and releases when the rail recovers above the threshold plus hysteresis — the pull-up resistor connects to the monitored rail or a separate bias supply depending on the reset hold time needed. At 4.2V, this part is sized for 5V nominal rails where the undervoltage lockout or power-good window must trigger before the downstream logic loses state. ## Package and board-fit — SOT-23-3 footprint Housed in the three-lead SOT-23-3 package (also designated TO-236-3 and SC-59), the part occupies roughly 3×1.5 mm board area — suited for tight layouts where a supervisor must sit near the rail's own decoupling capacitor. The supplier device package is SOT-23-3; the land pattern matches the standard JEDEC MO-178 variant. ## Active lifecycle — no obsolescence pressure RoHS non-compliance is the main compliance flag: the part contains lead in the termination finish or die-attach material. For BOMs that require RoHS exemption (e.g. certain industrial and aerospace applications), this may be acceptable under the standard exemptions; for full RoHS-compliance requirements, the buyer should verify the acceptance criteria before committing the BOM line.","metaTitle":"MAX6380UR42-T Voltage Detector, 4.2V Threshold, SOT-23-3","metaDescription":"MAX6380UR42-T from Analog Devices: voltage detector with 4.2V threshold, active-low open-drain reset, -40°C to 85°C range, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Type":"Voltage Detector","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Bulk","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.2V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-3","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2","stockQuantity":0,"priceTiers":[{"qty":251,"price":"$1.20000","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the MAX6380UR42-T's reset output type?","answer":"The reset output is active-low, open-drain (open collector)."},{"question":"What compliance documentation does Analog Devices provide for the MAX6380UR42-T?","answer":"The part is listed as RoHS non-compliant.
