The MAX6343ZUT: The reset output is active-low, open-drain, meaning the pin pulls to ground when the threshold is violated and floats high through an external pull-up resistor when the supply is valid. The reset timeout is a minimum of 100ms, providing a guaranteed hold time for the system to stabilise after the supply returns above threshold. Operating temperature spans -40°C to +125°C (TA), covering the industrial and automotive ambient range. This is the junction temperature limit for the internal comparator and reference, not a derated figure — the device can sit in an engine bay or a hot enclosure without requiring active cooling.
SOT-23-6 package and board integration
Housed in a 6-lead SOT-23 surface-mount package (SOT-23-6), the MAX6343ZUT occupies roughly 3×3 mm of board area. The supplier device package matches the case code — no footprint mismatch between the orderable part and the recommended land pattern. The open-drain output requires an external pull-up resistor to the logic supply rail.
RoHS compliance is listed as non-compliant. For designs requiring RoHS exemption (e.g., high-reliability or military applications where leaded solder is preferred), this is acceptable; for standard commercial RoHS-mandated builds, a pin-compatible RoHS-compliant variant from the same family should be evaluated.
