The active-low, push-pull output drives the reset line directly without an external pull-up resistor. It comes in a compact SC-70-3 package, sized for space-constrained boards in industrial control, telecom, and embedded systems where a clean power-on reset sequence is required. The 3V threshold is the trip point at which the reset asserts when the monitored supply drops below that level. For a 3.3V rail, this gives roughly 300mV of margin before a brownout triggers a reset — enough headroom for most linear regulators but tight if the rail is heavily loaded. If your design uses a fast-starting oscillator or a regulator with a slow ramp, verify that 100ms covers the full power-up sequence; otherwise, an external capacitor on the MR pin (if available on a sibling) extends the delay. ## Active-low push-pull output It drives the reset input of the monitored IC directly, sourcing or sinking current as needed. The active-low polarity is standard for most MCUs and DSPs — confirm the processor's reset input is active low before committing the BOM. The SC-70-3 (SOT-323) footprint is one of the smallest for a voltage supervisor, occupying roughly 2mm × 2mm of board area. Surface-mount assembly is straightforward for standard reflow profiles. The three-pin layout — VCC, GND, and RESET — keeps routing simple: place it close to the monitored IC's supply pin to minimise noise pickup on the sense line.","metaTitle":"MAX6326XR30 Simple Reset/Power-On Reset, 3V Threshold","metaDescription":"MAX6326XR30 is an active simple reset/power-on reset supervisor with 3V threshold, 100ms min timeout, active-low push-pull output in SC-70-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"100ms Minimum","Package / Case":"SC-70, SOT-323","lifecycle_stage":"eol_hot","Voltage - Threshold":"3V","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"SC-70-3","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.74","priceTiers":[{"qty":110,"price":"$2.74000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/649aba6b9d48496fffacc6200590e31d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX6326XR30/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout of MAX6326XR30?","answer":"The reset timeout is a minimum of 100ms. After the monitored voltage rises above the 3V threshold, the reset output remains asserted for at least 100ms before releasing the processor."},{"question":"Does MAX6326XR30 have an active-low reset output?","answer":"Yes, the reset output is active low with a push-pull (totem pole) stage. It drives the reset line low when the supply drops below the threshold and releases high after the timeout."},{"question":"What is the closest equivalent to MAX6326XR30?","answer":"Within the same MAX6326 family, the MAX6326XR30 is the 3V threshold variant. Other threshold options (e.g., 2.5V, 4.6V) share the same pinout and SC-70-3 package, so a threshold change is a direct drop-in substitution if the monitored rail voltage differs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6326XR30","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6326XR30 when reusing this data.
