It is designed for use in microcontroller systems, industrial controllers, and other digital logic circuits where a clean, glitch-free startup and brownout reset are required. The part is rated for the industrial temperature range of -40°C to 85°C, making it suitable for factory automation, outdoor telecom, and motor drive environments. ## 80 µs propagation delay — what it means for the reset timing budget The 80 µs typical propagation delay from the supply crossing the threshold to the reset output going active is the key timing parameter for this supervisor. In a typical MCU application, this delay must be shorter than the supply hold-up time of the downstream regulator to guarantee the reset is asserted before the logic rails collapse. The push-pull output eliminates the need for an external pull-up resistor, simplifying the BOM and saving board space in the SOT-143-4 package. ## Active production — no LTB risk for new designs The part is ROHS3 compliant, so it meets the current environmental compliance requirements for EU and global markets.","metaTitle":"MAX837EUS+T Simple Reset/Power-On Reset, SOT-143-4","metaDescription":"MAX837EUS+T is an active, simple reset/power-on reset supervisor with 80µs typical propagation delay, push-pull output, SOT-143-4, -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":"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":"80µs Typical Propagation Delay","Package / Case":"TO-253-4, TO-253AA","lifecycle_stage":"eol_hot","Voltage - Threshold":"Adjustable/Selectable","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-143-4","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.23","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.23000","currency":"USD"},{"qty":10,"price":"$3.79800","currency":"USD"},{"qty":25,"price":"$3.59040","currency":"USD"},{"qty":100,"price":"$3.11180","currency":"USD"},{"qty":250,"price":"$2.95224","currency":"USD"},{"qty":500,"price":"$2.64902","currency":"USD"},{"qty":1000,"price":"$2.23412","currency":"USD"},{"qty":2500,"price":"$1.98808","currency":"USD"},{"qty":5000,"price":"$1.91334","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX836-MAX837.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX837EUST","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX837EUST when reusing this data.
