It monitors a single supply voltage and asserts a reset output when the supply drops below a preset threshold, holding the reset for a timeout period after the supply recovers. This is the kind of part you drop onto a board to keep a microcontroller from running wild during power-up, brownout, or glitch events — no external timing capacitor needed, just the three pins. ## Lifecycle and compliance — what to expect One catch: it is marked RoHS non-compliant. If your BOM calls for lead-free assembly per EU directives or internal RoHS mandates, this part will not pass a materials declaration audit. That is a hard gate for new designs in regulated markets; for legacy or exempt military/industrial builds it may still be acceptable. ## Sourcing this part The MAX803LEXR is available through independent distribution channels. Because it is an active part with no LTB pressure, lead times tend to be stable — but the RoHS flag means you want to verify your assembly line's exemption status before committing the BOM line.","metaTitle":"MAX803LEXR 3-Pin MPU Supervisor, Active, Bulk","metaDescription":"MAX803LEXR is an active 3-pin MPU supervisor from Maxim Integrated.","metaKeywords":null},"attributes":{"series":"*","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"*","Package":"Bulk","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.85","stockQuantity":0,"priceTiers":[{"qty":163,"price":"$1.85000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9c7e2c562506e1ad3fe2630ef58628cb.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX803LEXR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX803LEXR when reusing this data.
