It comes in a SOT-23-5 package — the same footprint as a small-signal transistor — and fits tight mixed-voltage boards where a second processor or an FPGA core rail needs its own watchdog. ## What the dual-threshold setup means on the bench One channel has a fixed 2.313 V threshold — typical for a 2.5 V logic rail — and the second channel is adjustable via an external resistor divider, so you set the trip point for a 1.8 V, 3.3 V, or any intermediate rail. The reset output is push-pull and active high, meaning it drives the reset line high on a fault and holds it there for an adjustable timeout period set by a capacitor. That capacitor-programmed delay lets you skip the glitch during power-up sequencing without adding a separate delay IC. The SOT-23-5 package is one of the easiest to rework by hand — five pins, visible leads, no thermal pad underneath. A standard hot-air station at 300°C with a fine tip lifts the part cleanly without lifting adjacent pads.","metaTitle":"MAX6419UK23-T Multi-Voltage Supervisor, SOT-23-5","metaDescription":"MAX6419UK23-T dual-channel supervisor from Analog Devices, 2.313V fixed threshold plus adjustable channel, active-high push-pull reset, SOT-23-5, -40°C to","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Type":"Multi-Voltage Supervisor","Reset":"Active High","Output":"Push-Pull, Totem Pole","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"Adjustable/Selectable","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Voltage - Threshold":"2.313V, Adj","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.21","stockQuantity":0,"priceTiers":[{"qty":249,"price":"$1.21000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/928f6991ea013600a59314b78808f805.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy MAX6419UK23-T and get a price?","answer":"The MAX6419UK23-T is available to order through our independent distribution channel."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6419UK23-T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6419UK23-T when reusing this data.
