The 2.925V threshold sits right around the 3.0V logic rail brownout zone: if your 3.3V supply dips below about 88% of nominal, the STM804SM6F flags it before the processor's internal POR loses margin. The open-drain output lets you wire-OR multiple supervisors to a shared reset line without contention. ## Industrial temp range and package fit The 8-SOIC (150-mil body) footprint is a standard surface-mount package with 1.27mm pin pitch, so it routes on a two-layer board without via congestion under the body. The supplier device package is 8-SOIC, same as the package/case field. ## Sourcing posture For BOM-line matching, the key fit parameters are the 2.925V threshold, active-high open-drain output, and 140ms minimum reset timeout; confirm these against your processor's reset input requirements before committing the line.","metaTitle":"STM804SM6F Supervisor IC, 2.925V Threshold, 8-SOIC","metaDescription":"STMicroelectronics STM804SM6F simple reset/power-on reset IC, active high, open drain output, 140ms timeout, 2.925V threshold, -40 to 85°C, 8-SOIC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active High","Output":"Open Drain or Open Collector","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Threshold":"2.925V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"8-SOIC","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.94","priceTiers":[{"qty":1,"price":"$3.94000","currency":"USD"},{"qty":10,"price":"$3.53500","currency":"USD"},{"qty":25,"price":"$3.34200","currency":"USD"},{"qty":100,"price":"$2.89650","currency":"USD"},{"qty":250,"price":"$2.74796","currency":"USD"},{"qty":500,"price":"$2.46572","currency":"USD"},{"qty":1000,"price":"$2.45228","currency":"USD"},{"qty":2500,"price":"$2.45228","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/13c3ef00103aab18295f01fe57716cda.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM804SM6F/alternatives.json"},"ai":{"faq":[{"question":"Will STM804SM6F drop into a board designed for STM804RM6F?","answer":"The STM804SM6F and STM804RM6F share the same package (8-SOIC), reset type (active high), output type (open drain), and reset timeout (140ms minimum). The difference is the threshold voltage: STM804SM6F triggers at 2.925V, while STM804RM6F triggers at a different threshold. If your board's threshold requirement matches 2.925V, the STM804SM6F is a drop-in replacement at the footprint level."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM804SM6F","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM804SM6F when reusing this data.
