It monitors a 3.3V threshold on the primary channel and two additional adjustable inputs, making it a fit for multi-voltage designs in industrial control, telecom line cards, and embedded systems where power-up sequencing prevents latch-up or bus contention. The active-low reset output is open-drain, so it can be wire-ORed with other reset sources or pulled up to a different voltage rail. The reset timeout is factory-selectable among 10ms, 20ms, or 50ms minimum durations, which lets you match the power-good hold-off to the slowest rail's ramp time without external timing components. ## Package and temperature grade for industrial environments Housed in an 8-uMAX/uSOP package (3.00mm width, 0.118\" pitch), the DS1830AU+ is a surface-mount device suited for dense PCB layouts where board area is at a premium. The -40°C to +85°C operating temperature range covers industrial and outdoor telecom enclosures, so it can sit on a motor-drive control board or a base-station power module without derating concerns. ## Active production — no last-time-buy risk This is a production-grade part you can qualify into a new BOM without worrying about a surprise discontinuation notice mid-cycle. ROHS3 compliant per the listing.","metaTitle":"Maxim DS1830AU+ 3-Channel Sequencer, 3.3V Threshold, 8-uMAX","metaDescription":"Maxim DS1830AU+ 3-channel voltage sequencer with active-low reset, open-drain output, configurable 10/20/50ms timeout. 8-uMAX package, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Sequencer","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Tube","Mounting Type":"Surface Mount","Reset Timeout":"10ms; 20ms; 50ms Minimum","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Voltage - Threshold":"3.3V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-uMAX/uSOP","Number of Voltages Monitored":"3"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.01","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.01000","currency":"USD"},{"qty":10,"price":"$4.49500","currency":"USD"},{"qty":25,"price":"$4.24960","currency":"USD"},{"qty":100,"price":"$3.68300","currency":"USD"},{"qty":250,"price":"$3.49408","currency":"USD"},{"qty":500,"price":"$3.13524","currency":"USD"},{"qty":1000,"price":"$2.64418","currency":"USD"},{"qty":2500,"price":"$2.51197","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/DS1830-DS1830A.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between DS1830AU and DS1830AU+?","answer":"The DS1830AU+ is the ROHS3-compliant lead-free variant of the DS1830AU.
