It monitors a single supply rail and asserts a reset signal when the voltage drops below a threshold, holding the reset active for a minimum of 140 ms after the supply recovers. The open-drain output lets you wire-OR it with other reset sources or pull it up to a different logic voltage. ## Package and rework considerations The SOT-23-5 package is straightforward to hand-solder and rework. The small footprint and low thermal mass mean it reflows cleanly with a standard hot-air profile. ## Lifecycle and sourcing The MAX6845UKD3+T is listed as Active on the manufacturer's lifecycle status, with ROHS3 compliance. There is no end-of-life notice or last-time-buy window, so it remains a safe choice for production builds.","metaTitle":"MAX6845UKD3+T Simple Reset/Power-On Reset, Active Low","metaDescription":"MAX6845UKD3+T is an active supervisor IC with open-drain output, 140ms min reset timeout, and industrial temp range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Voltage - Threshold":"Adjustable/Selectable","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.26","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.26000","currency":"USD"},{"qty":10,"price":"$3.82200","currency":"USD"},{"qty":25,"price":"$3.61320","currency":"USD"},{"qty":100,"price":"$3.13150","currency":"USD"},{"qty":250,"price":"$2.97092","currency":"USD"},{"qty":500,"price":"$2.66580","currency":"USD"},{"qty":1000,"price":"$2.24826","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX6841-MAX6845.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX6845UKD3+T obsolete?","answer":"No, the MAX6845UKD3+T is listed as Active on the manufacturer's lifecycle status with no end-of-life notice."},{"question":"Does MAX6845UKD3+T have an open drain output?","answer":"Yes, the output is open drain or open collector, which allows it to be pulled up to a different voltage or wire-ORed with other open-drain signals."},{"question":"What is the reset timeout of MAX6845UKD3+T?","answer":"The reset timeout is a minimum of 140 ms, ensuring the processor is held in reset long enough for the supply to stabilize after a brownout or power-up."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6845UKD3T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6845UKD3T when reusing this data.
