It asserts a reset signal (active low) via an open-drain or open-collector output, giving the system designer flexibility to tailor the reset pulse width to match the downstream processor or FPGA requirements. This is not a simple fixed-delay reset generator; the timeout is configurable, so one BOM line can serve multiple reset timing needs across a product family by changing a single external component. Housed in a 6-UDFN package (1.45x1 mm body), it is a surface-mount part suited for space-constrained PCBs in industrial control, telecom, and embedded systems where a clean, adjustable reset sequence is needed. The adjustable/selectable reset timeout lets you set the reset pulse width via an external timing component. The open-drain output allows the reset line to be shared with other reset sources or level-shifted via an external pull-up resistor.","metaTitle":"STMicroelectronics STM6519AHARUB6F Smart Reset Timer, 6-UDFN","metaDescription":"STMicroelectronics STM6519AHARUB6F Smart Reset™ supervisor, reset timer with adjustable timeout, open-drain output, -40°C to 85°C, 6-UDFN.","metaKeywords":null},"attributes":{"series":"Smart Reset™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Reset Timer","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"Smart Reset™","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"Adjustable/Selectable","Package / Case":"6-UFDFN","lifecycle_stage":"eol_hot","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"6-UDFN (1.45x1)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2","priceTiers":[{"qty":1,"price":"$1.20000","currency":"USD"},{"qty":10,"price":"$1.07200","currency":"USD"},{"qty":25,"price":"$1.01760","currency":"USD"},{"qty":100,"price":"$0.83600","currency":"USD"},{"qty":250,"price":"$0.78148","currency":"USD"},{"qty":500,"price":"$0.69060","currency":"USD"},{"qty":1000,"price":"$0.60008","currency":"USD"},{"qty":3000,"price":"$0.60007","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f935ed4cd81adfd192a1caacaf8560be.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM6519AHARUB6F/alternatives.json"},"ai":{"faq":[{"question":"Is STM6519AHARUB6F active or obsolete?","answer":"It is Active in production with no end-of-life notice.

The STM809TWX6F and STM706M6F offer fixed 140 ms minimum reset timeout but use push-pull outputs. None are direct pin-compatible drop-ins; the choice depends on whether you need the adjustable timeout and open-drain flexibility."},{"question":"How does the adjustable reset timeout work on STM6519AHARUB6F?","answer":"The reset timeout is adjustable/selectable via an external timing component (capacitor or resistor). The exact range and formula are in the datasheet; the key point is that one supervisor IC can be configured for different reset pulse widths by changing that external component."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM6519AHARUB6F","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM6519AHARUB6F when reusing this data.
