The reset output remains asserted for a minimum of 140ms after the supply recovers, providing a clean startup sequence for microprocessors, DSPs, or FPGAs. The open-drain output allows wired-OR connection with other reset sources and requires an external pull-up resistor to the monitored rail or another logic voltage. This part is a straightforward, no-frills supervisor for a 3V system where the designer needs a guaranteed reset pulse and does not require manual reset input or watchdog timer functionality. ## Temperature grade and environment Rated for operation from -40°C to 125°C, this part handles the full industrial temperature span and reaches into automotive under-hood environments. The wide range means it can sit on a motor drive PCB near heat-generating power stages, in an outdoor telecom enclosure, or in an engine bay electronics module without derating concerns. The SOT-23-4 package keeps the board footprint small — useful when the supervisor is placed close to the supervised processor, not at a central power distribution point. ## Lifecycle and supply position Listed as Active on the manufacturer's lifecycle status. ## 140ms reset timeout — what it means for system boot The 140ms minimum reset timeout allows power supplies to settle after brown-out or power-up before the processor starts executing code.","metaTitle":"MAX6315US30D3+ Simple Reset/Power-On Reset, 3V Threshold","metaDescription":"MAX6315US30D3+ from Analog Devices is a simple reset/power-on reset IC with active-low open-drain output, 140ms minimum reset timeout, 3V threshold, -40°C to","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"140ms Minimum","Package / Case":"TO-253-4, TO-253AA","lifecycle_stage":"eol_hot","Voltage - Threshold":"3V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-23-4","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.25","stockQuantity":0,"priceTiers":[{"qty":283,"price":"$1.25000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/db2bc80a276123926c344f631d0f479c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the reset timeout of MAX6315US30D3+?","answer":"The reset timeout is 140ms minimum.
