That duration is typical for many MCUs and SoCs; if your part needs a longer or shorter delay, the timeout here is fixed and not adjustable. For designs that need a custom delay, a supervisor with an external timing capacitor would be the alternative. ## Industrial temperature range Rated for -40°C to 85°C ambient, this supervisor suits factory automation, outdoor telecom enclosures, and other environments where the board sees seasonal or process heat. The SOT-23-5 package is small enough to place close to the monitored rail without crowding the layout.","metaTitle":"DS1819AR-5+T&R Simple Reset/Power-On Reset, 3.075V Threshold","metaDescription":"Maxim Integrated DS1819AR-5+T&R is an active MicroMonitor™ simple reset/power-on reset IC with 3.075V threshold, 140ms timeout, push-pull output, SOT-23-5.","metaKeywords":null},"attributes":{"series":"MicroMonitor™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Series":"MicroMonitor™","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":"3.075V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.97","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.97000","currency":"USD"},{"qty":10,"price":"$5.36000","currency":"USD"},{"qty":25,"price":"$5.06760","currency":"USD"},{"qty":100,"price":"$4.39200","currency":"USD"},{"qty":250,"price":"$4.16676","currency":"USD"},{"qty":500,"price":"$3.73882","currency":"USD"},{"qty":1000,"price":"$3.15322","currency":"USD"},{"qty":3000,"price":"$2.99556","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6c1cd77041184f7f2eaa7dcab1c32a9a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reset timeout for DS1819AR-5+T&R?","answer":"The reset timeout is a minimum of 140ms after the supply rail rises above the 3.075V threshold.
