The SOT-23-6 package keeps the board footprint small — useful when the supervisor sits near the processor on a dense mixed-signal board. ## Threshold selection and temperature range The fixed threshold of 3.075V suits a 3.3V rail with a typical tolerance band — the supervisor asserts reset when the supply dips below roughly 2.9V to 3.0V (the exact trip point is set by the internal bandgap). The adjustable channel on the second input lets the designer set the trip voltage for a lower rail, such as 1.8V or 1.2V core supply, using a pair of resistors to the reference pin. The reset timeout of 140ms minimum is long enough to cover the startup ramp of a ceramic-capacitor-based buck converter but short enough that the processor does not miss a real-time communication window on power-up. Sourced through independent distribution channels. The date-code and lot traceability are verified before shipment — the package marking and tape-and-reel label must match the manufacturer's plant format for the production week.","metaTitle":"STM6780TWB6F Multi-Voltage Supervisor, 3.075V Threshold","metaDescription":"STMicroelectronics STM6780TWB6F multi-voltage supervisor, active low reset, 2 channels, 3.075V threshold plus adjustable, 140ms timeout, SOT-23-6.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Type":"Multi-Voltage Supervisor","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"SOT-23-6","lifecycle_stage":"eol_hot","Voltage - Threshold":"3.075V, Adj","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.63","priceTiers":[{"qty":1,"price":"$1.63000","currency":"USD"},{"qty":10,"price":"$1.46800","currency":"USD"},{"qty":25,"price":"$1.38520","currency":"USD"},{"qty":100,"price":"$1.18020","currency":"USD"},{"qty":250,"price":"$1.10816","currency":"USD"},{"qty":500,"price":"$0.96966","currency":"USD"},{"qty":1000,"price":"$0.80342","currency":"USD"},{"qty":3000,"price":"$0.74802","currency":"USD"},{"qty":6000,"price":"$0.72031","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/776643b4044dd6a7f1f7fffd6fbad29d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM6780TWB6F/alternatives.json"},"ai":{"faq":[{"question":"Does STM6780TWB6F have an adjustable threshold?","answer":"Yes. The STM6780TWB6F monitors two voltages: one fixed at 3.075V and one adjustable via an external resistor divider. The adjustable channel lets you set the trip point for a second rail, such as 1.2V, 1.8V, or any voltage below the reference input range."},{"question":"What is the closest alternative to STM6780TWB6F?","answer":"The STM6780VWB6F is the same two-channel supervisor in the same SOT-23-6 package with the same 140ms reset timeout and active-low push-pull output. The difference is the fixed threshold — verify the VWB6F variant's fixed threshold matches your 3.3V rail tolerance before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM6780TWB6F","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM6780TWB6F when reusing this data.
