It monitors a single voltage rail with a 4.63V threshold and asserts a reset signal when the supply drops below that level. The active-low, open-drain output lets multiple supervisors share a common reset bus via a pull-up resistor — a common arrangement in multi-rail systems where any one rail fault must trigger a system-wide reset. The 100ms minimum reset timeout gives the processor and peripherals time to stabilize after the supply returns. ## Temperature range and deployment environment Rated from -40°C to 125°C, this part is specified for industrial and automotive under-hood environments. The extended temperature range covers the thermal cycling found in engine bays, factory-floor enclosures, and outdoor telecom cabinets. If your BOM calls for a supervisor that holds its threshold across a wide ambient swing, this is the tier to specify. ## Package and mounting Housed in a SOT-143-4 surface-mount package, the MAX6805US46D3+T occupies minimal board area and is compatible with standard reflow profiles. The four-pin footprint — VCC, GND, RESET, and a no-connect — is a common supervisor layout, making it a drop-in fit for many existing PCB designs that use a similar pinout. ## Lifecycle and compliance The MAX6805US46D3+T is listed as active in production with ROHS3 compliance. For a BOM freeze, this part carries no near-term obsolescence risk. The ROHS3 status covers the current exemption list, so it meets EU and most global environmental requirements without a waiver.","metaTitle":"MAX6805US46D3+T Simple Reset/Power-On Reset, 4.63V Threshold","metaDescription":"MAX6805US46D3+T is a simple reset/power-on reset IC with 4.63V threshold, active-low open-drain output, 100ms timeout, -40°C to 125°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"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":"100ms Minimum","Package / Case":"TO-253-4, TO-253AA","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.63V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-143-4","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.65","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.65000","currency":"USD"},{"qty":10,"price":"$5.07200","currency":"USD"},{"qty":25,"price":"$4.79480","currency":"USD"},{"qty":100,"price":"$4.15560","currency":"USD"},{"qty":250,"price":"$3.94252","currency":"USD"},{"qty":500,"price":"$3.53762","currency":"USD"},{"qty":1000,"price":"$2.98354","currency":"USD"},{"qty":2500,"price":"$2.83436","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX6803-MAX6805.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MAX6805US46D3+T?","answer":"The MAX6805US46D2+T is a direct variant with a different threshold voltage (4.63V vs the D2's threshold). Both share the same SOT-143-4 package, active-low open-drain output, and 100ms timeout. The D3 suffix indicates the 4.63V threshold; the D2 uses a different trip point. If your design requires the exact 4.63V threshold, the D3 is the correct choice."},{"question":"Can MAX6805US46D3+T be used with a 3.3V supply?","answer":"No — the threshold is 4.63V, so the part monitors a 5V rail, not a 3.3V one. For a 3.3V rail, you would need a supervisor with a lower threshold, such as the MAX6805US33D3+T or a similar variant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6805US46D3T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6805US46D3T when reusing this data.
