That open-drain output lets you wire-OR multiple supervisors or pull up to a different logic voltage than the monitored rail. ## 140ms reset timeout — why the delay matters That delay gives the power supply and oscillator time to stabilise before the processor starts executing code — without it, the CPU could boot into an undefined state from a rail that hasn't fully settled. The device monitors only one voltage, so it fits designs where a single critical rail — typically the core or I/O supply — needs supervision. For multi-rail systems you'd stack multiple instances or use a multi-voltage supervisor. ## Active production — no end-of-life pressure for this BOM line The part ships in a SOT-143-4 surface-mount package (also referred to as TO-253-4 / TO-253AA), a common footprint for small-outline transistor and supervisor ICs.","metaTitle":"MAX6444US46L+T Analog Devices Simple Reset/Power-On Reset","metaDescription":"MAX6444US46L+T from Analog Devices — Simple Reset/Power-On Reset IC, active-low open-drain output, 4.625V threshold, SOT-143-4.","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 Low","Output":"Open Drain or Open Collector","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"TO-253-4, TO-253AA","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.625V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-143-4","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.08","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.08000","currency":"USD"},{"qty":10,"price":"$5.45700","currency":"USD"},{"qty":25,"price":"$5.15840","currency":"USD"},{"qty":100,"price":"$4.47080","currency":"USD"},{"qty":2500,"price":"$3.04929","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6444US46LT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6444US46LT when reusing this data.
