It has passed stress tests for under-hood and chassis-domain electronics. ## Package and footprint Housed in a 6-WFDFN (6-uDFN 1.5x1 mm) surface-mount package, the MAX6381LT44D3+ occupies minimal board area. The supplier device package is 6-uDFN (1.5x1). The small footprint suits space-constrained designs — sensor modules, compact ECU boards, or multi-rail PMICs where each supervisor is placed close to its monitored rail. No through-hole option; this is a surface-mount-only part. ## Sourcing and lifecycle Listed as Active on the lifecycle record, the MAX6381LT44D3+ is current-production and RoHS3 compliant. There is no NRND or last-time-buy flag.","metaTitle":"MAX6381LT44D3+ Power Supply Monitor, AEC-Q100","metaDescription":"MAX6381LT44D3+ is an automotive-qualified (AEC-Q100) power supply monitor with active-low reset, 140ms minimum timeout, and -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"4.38V","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":"Is MAX6381LT44D3+ automotive qualified?","answer":"Yes, it is AEC-Q100 qualified, rated for the -40°C to 125°C operating temperature range, making it suitable for automotive under-hood and chassis-domain applications."},{"question":"What is the difference between MAX6381LT44D3+ and MAX6381LT44D3+T?","answer":"The suffix +T typically indicates tape-and-reel packaging.
