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. ## 3V threshold and 100ms timeout — what they mean for the BOM 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. The 100ms minimum reset timeout ensures the core supply and oscillator have stabilised before the processor starts executing code. 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 The push-pull output eliminates the need for an external pull-up resistor to the supply rail, saving one component and one PCB trace. 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. ## Package and mounting 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. ## Lifecycle and sourcing It is RoHS non-compliant as listed, so verify your assembly house's exemption policy if you require RoHS compliance.","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":["Discrete Semiconductors"],"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","stockQuantity":0,"priceTiers":[{"qty":110,"price":"$2.74000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/649aba6b9d48496fffacc6200590e31d.pdf","sourceUrl":null},"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.
