This is a simple reset/power-on reset part — no watchdog timer, no manual reset input, no adjustable delay. The active-high push-pull output drives directly into the reset pin of an MCU or SoC that expects a logic-high during reset. ## Package and footprint — SOT-23-5 Housed in a 5-pin SOT-23-5 (SC-74A) package, surface-mount only. No thermal pad to worry about — dissipation is low for this class of device. The ROHS3 status means it meets the latest EU restriction exemption rules.","metaTitle":"MAX6821TUK+T Simple Reset/Power-On Reset, 3.08V Threshold","metaDescription":"MAX6821TUK+T from Analog Devices: Simple Reset/Power-On Reset, active high push-pull output, 3.08V threshold, 140ms timeout, -40°C to 125°C, SOT-23-5.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Type":"Simple Reset/Power-On Reset","Reset":"Active High","Output":"Push-Pull, Totem Pole","Package":"Bulk","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Voltage - Threshold":"3.08V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.46","priceTiers":[{"qty":207,"price":"$1.46000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f89f0440af3d221290f329e043e1e65f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MAX6821TUK%2BT/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to MAX6821TUK+T?","answer":"The MAX6820TUK+T is the same-function sibling — also a simple reset/power-on reset in SOT-23-5, but with an active-low output instead of active-high. If your design expects a logic-low during reset, the MAX6820TUK+T is the direct swap.
