SC-70-4 footprint and integration
The MAX6839XSD3 comes in a SC-70-4 package (also known as SC-82A, SOT-343), which is a compact surface-mount package with four leads. The supplier device package is SC-70-4, so the PCB footprint matches the standard SC-70-4 land pattern — no special pad geometry required. The reset is active high, meaning the output goes high when the monitored voltage is within tolerance — a less common polarity that matters for the downstream logic interface.
