It is the watchdog between the regulator and the downstream logic, sized for board-level supervision in systems that need a clean, deterministic power-on and power-off sequence. ROHS3 compliant, so it clears the EU material restrictions without an exemption review. ## Lifecycle and sourcing posture The UC3910DTR carries an Active product status — no last-time-buy clock ticking, no EOL notice to track. That means it can be specified into a new BOM without planning an early migration.","metaTitle":"UC3910DTR IC SUPERVISOR PWR SUP SUPPORT, Active, ROHS3","metaDescription":"UC3910DTR is an active IC supervisor for power supply support, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":"*","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"*","Package":"Bulk","lifecycle_stage":"eol_hot"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.97","stockQuantity":0,"priceTiers":[{"qty":153,"price":"$1.97000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c7b3b84e0bea85f7d9a53bb967ef6186.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the UC3910DTR used for?","answer":"The UC3910DTR is a supervisor IC for power supply support, used to monitor voltage rails and assert reset or fault signals in systems requiring reliable power sequencing."},{"question":"What is the UC3910DTR replacement or equivalent?","answer":"No official replacement or second-source alternate is recorded for the UC3910DTR.
