It offers both active-high and active-low reset outputs, configurable as open drain or push-pull, so it can interface with a wide range of SoC reset inputs without external level translation. The timeout is adjustable via an external capacitor, letting you tailor the reset pulse width to the power-up sequencing requirements of FPGAs, MCUs, or mixed-voltage systems. The device operates over -30°C to 85°C, suiting it for industrial control panels, base station equipment, and outdoor telecom enclosures where the board temperature stays within that range. ## Output configuration and reset polarity — what to watch on the BOM Because the reset output can be either open drain or push-pull, the BOM pull-up resistor is conditional. If you configure the output as open drain, a pull-up to the appropriate rail is required; push-pull mode eliminates that resistor and provides a rail-to-rail drive. The dual active-high/active-low polarity means the same part can serve a processor that expects a logic-high reset and one that expects a logic-low, simplifying inventory across different board designs. ## Package and footprint — 8-TDFN (2x2 mm) Housed in an 8-TDFN package measuring 2x2 mm, the STM6520AQRRDG9F occupies minimal board area. The small footprint is a fit for space-constrained designs like handheld instruments or compact sensor nodes. It carries ROHS3 compliance, so it meets current environmental requirements for EU and global markets.","metaTitle":"STM6520AQRRDG9F Smart Reset Timer, Active High/Low, 8-TDFN","metaDescription":"STMicroelectronics STM6520AQRRDG9F Smart Reset Timer with adjustable timeout, active high/low reset, open drain/push-pull output. -30°C to 85°C.","metaKeywords":null},"attributes":{"series":"Smart Reset™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Reset Timer","Reset":"Active High/Active Low","Output":"Open Drain, Push-Pull","Series":"Smart Reset™","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"Adjustable/Selectable","Package / Case":"8-WFDFN","lifecycle_stage":"eol_hot","Operating Temperature":"-30°C ~ 85°C (TA)","Supplier Device Package":"8-TDFN (2x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.37","priceTiers":[{"qty":1,"price":"$1.37000","currency":"USD"},{"qty":10,"price":"$1.22600","currency":"USD"},{"qty":25,"price":"$1.16360","currency":"USD"},{"qty":100,"price":"$0.95590","currency":"USD"},{"qty":250,"price":"$0.89356","currency":"USD"},{"qty":500,"price":"$0.78966","currency":"USD"},{"qty":1000,"price":"$0.62342","currency":"USD"},{"qty":3000,"price":"$0.58186","currency":"USD"},{"qty":6000,"price":"$0.55277","currency":"USD"},{"qty":15000,"price":"$0.53199","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4c6bcec33ae9045e2ce1c000b5b01faa.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM6520AQRRDG9F/alternatives.json"},"ai":{"faq":[{"question":"How does STM6520AQRRDG9F work?","answer":"The device monitors the supply voltage and, after the supply crosses the threshold, generates a reset pulse whose duration is set by an external capacitor.
