One channel has a fixed 4.43 V threshold; the second channel accepts an adjustable threshold set by an external resistor divider, giving flexibility to monitor a secondary rail at any voltage below the reference. The active-low, open-drain output allows multiple supervisor outputs to be wire-OR'd to a common reset line, a common topology in multi-rail systems where any fault must assert a system-wide reset. ## Reset timing and output behaviour A minimum 140 ms reset timeout holds the output low after the monitored voltages rise above their thresholds, giving the system clock and core logic time to stabilise before the processor starts executing code. The open-drain output requires an external pull-up resistor to the desired logic rail; it sinks current when asserting reset and releases to high-impedance when the timeout expires. With two monitored voltages, this supervisor replaces two single-channel supervisor ICs, saving board area and reducing BOM count in space-constrained designs. ## Package and temperature range Housed in a 5-pin SOT-23 (SC-74A) package, the MIC2774N-44YM5 is a surface-mount device suited for automated assembly in compact PCB layouts.","metaTitle":"MIC2774N-44YM5 Multi-Voltage Supervisor, 4.43V/Adj, SOT-23-5","metaDescription":"Microchip MIC2774N-44YM5 multi-voltage supervisor monitors two rails with 4.43V fixed and adjustable thresholds, 140ms reset timeout, active-low open-drain","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Type":"Multi-Voltage Supervisor","Reset":"Active Low","Output":"Open Drain or Open Collector","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Voltage - Threshold":"4.43V, Adj","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.37","priceTiers":[{"qty":879,"price":"$0.37000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f3f801eecd0fb0d65bcaf1a3e7aa307c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MIC2774N-44YM5/alternatives.json"},"ai":{"faq":[{"question":"What does the 4.43V and adjustable threshold mean for my design?","answer":"The fixed 4.43 V channel is intended for monitoring a 5 V supply rail; the adjustable channel uses an external resistor divider to set a threshold for a second rail, such as 3.3 V, 2.5 V, or 1.8 V, giving flexibility without requiring a different supervisor part number."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/MIC2774N-44YM5","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/MIC2774N-44YM5 when reusing this data.
