The open-drain output stays low for a minimum of 100ms after the supply returns above threshold, giving the downstream processor or FPGA time to stabilize before release. This is a straightforward power-on reset part — no watchdog, no manual reset input, just the core supervisor function in a three-pin SOT-23-3 package. ## Threshold and timeout — what they mean for your BOM The 4V threshold monitors a 5V nominal rail. The 100ms minimum reset timeout covers most power-supply ramp-up and brown-out recovery sequences. ## Open-drain output — wiring and level translation The open-drain output lets you pull the reset line to any voltage up to the absolute maximum of the pin, independent of the supervisor's supply. ## Temperature range and environment Rated for -40°C to +85°C ambient, this part suits industrial and commercial environments. ## Lifecycle and sourcing posture Sourced through independent distribution and quoted to order against an RFQ.","metaTitle":"MAX6348UR40 Simple Reset/Power-On Reset, 4V Threshold","metaDescription":"MAX6348UR40 is a simple reset/power-on reset IC with 4V threshold, active-low open-drain output, 100ms reset timeout, in SOT-23-3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"100ms Minimum","Package / Case":"TO-236-3, SC-59, SOT-23-3","lifecycle_stage":"eol_hot","Voltage - Threshold":"4V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-3","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.74","stockQuantity":0,"priceTiers":[{"qty":110,"price":"$2.74000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/649aba6b9d48496fffacc6200590e31d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reset timeout of MAX6348UR40?","answer":"The reset timeout is a minimum of 100ms.
