The 140ms minimum reset timeout holds the reset line low long enough for the downstream device to complete its internal reset sequence after the supply stabilises. Operating temperature spans -40°C to +125°C, covering the full automotive ambient range including under-hood and cabin environments. ## 6-uDFN package — board-fit checklist The 6-uDFN (1.5x1) package is a 6-lead, 1.5mm × 1.0mm plastic DFN with an exposed pad. The supplier device package is 6-uDFN (1.5x1), and the mounting is surface-mount only. The small footprint saves board space but demands a well-designed solder stencil and reflow profile for the exposed pad — the pad acts as the primary thermal path, so the PCB copper landing should match the package outline for effective heat spreading.","metaTitle":"MAX6381LT29D3+ Power Supply Monitor, 2.93V Threshold","metaDescription":"Analog Devices MAX6381LT29D3+ power supply monitor, active-low reset, 2.93V threshold, 140ms timeout, AEC-Q100, -40°C to +125°C, 6-uDFN.","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":"140ms Minimum","Package / Case":"6-WFDFN","lifecycle_stage":"eol_hot","Voltage - Threshold":"2.93V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"6-uDFN (1.5x1)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.37","stockQuantity":0,"priceTiers":[{"qty":219,"price":"$1.37000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2a43ef6f52c719a0bf0ab10173c69901.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reset output type and timeout for MAX6381LT29D3+?","answer":"The reset output is active-low, push-pull (totem pole), with a minimum reset timeout of 140ms.
