If your board lives inside a motor drive or near an exhaust manifold, this temperature grade is what you need. ## Package and footprint Housed in a SOT-143-4 surface-mount package, it takes up roughly the same board area as a small-signal transistor. The pinout is standard for this class of supervisor — you can swap it into a layout originally designed for a pin-compatible part without a board spin. ## Lifecycle and compliance It is ROHS3 compliant, so it passes the material declaration gate for EU and California markets without an exemption certificate.","metaTitle":"MAX821PUS+T Simple Reset/Power-On Reset IC, 4V Threshold","metaDescription":"MAX821PUS+T from Analog Devices: 1-channel supervisor, active-low push-pull output, 4V threshold, adjustable timeout, -40°C to 125°C, SOT-143-4, RoHS3","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"Adjustable/Selectable","Package / Case":"TO-253-4, TO-253AA","lifecycle_stage":"eol_hot","Voltage - Threshold":"4V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-143-4","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.64","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.64000","currency":"USD"},{"qty":10,"price":"$3.26900","currency":"USD"},{"qty":25,"price":"$3.09040","currency":"USD"},{"qty":100,"price":"$2.67850","currency":"USD"},{"qty":250,"price":"$2.54116","currency":"USD"},{"qty":500,"price":"$2.28018","currency":"USD"},{"qty":1000,"price":"$1.92304","currency":"USD"},{"qty":2500,"price":"$1.71942","currency":"USD"},{"qty":5000,"price":"$1.65478","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX821-MAX822T.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is MAX821PUS+T RoHS compliant?","answer":"Yes, it is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX821PUST","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX821PUST when reusing this data.
