It asserts an active-low, open-drain reset output when any monitored voltage falls below its threshold, holding the reset for a user-selectable timeout of 10ms, 100ms, or 1000ms minimum. Packaged in a 16-SOIC (0.154\" body width, 3.90mm) for surface-mount assembly. ## What the four monitored channels mean for your board With four independent voltage monitors, the DS1831S+ covers the core rails of a mixed-voltage design — e.g., a 5V analog supply, 3.3V I/O, and two adjustable rails for a 1.8V core and 1.2V auxiliary. The open-drain outputs can be wire-ORed with other supervisors or pulled up to the lowest rail for a single system reset line. The adjustable thresholds use external resistor dividers, letting you set trip points anywhere within the supply range without changing the IC.","metaTitle":"DS1831S+ Analog Devices Multi-Voltage Supervisor, 16-SOIC","metaDescription":"DS1831S+ Multi-Voltage Supervisor from Analog Devices, monitors four voltages (3.3V, 5V, Adj, Adj), active-low open-drain reset, 16-SOIC.","metaKeywords":null},"attributes":{"series":"MicroMonitor™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Multi-Voltage Supervisor","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"MicroMonitor™","Package":"Tube","Mounting Type":"Surface Mount","Reset Timeout":"10ms; 100ms; 1,000ms Minimum","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Threshold":"3.3V, 5V, Adj, Adj","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"16-SOIC","Number of Voltages Monitored":"4"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.44","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.44000","currency":"USD"},{"qty":10,"price":"$7.62200","currency":"USD"},{"qty":25,"price":"$7.26760","currency":"USD"},{"qty":100,"price":"$6.31030","currency":"USD"},{"qty":250,"price":"$6.02668","currency":"USD"},{"qty":500,"price":"$5.49490","currency":"USD"},{"qty":1000,"price":"$4.78588","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What voltages does the DS1831S+ monitor?","answer":"It monitors four voltages: fixed thresholds at 3.3V and 5V, plus two adjustable thresholds set by external resistors."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/DS1831S","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/DS1831S when reusing this data.
