The SOT-23-8 package (supplier device package same) is a compact surface-mount footprint, 8 pins, suitable for dense layouts. The open-drain output lets you pull up to any voltage up to the absolute maximum of the device, which is useful for level-shifting the reset signal to a lower-voltage core.
Note that it is RoHS non-compliant, which may affect its use in regions or applications requiring RoHS compliance.
It comes in an SOT-23-8 surface-mount package, with the supplier device package also being SOT-23-8.
Yes, the 4.38V threshold is designed for monitoring a nominal 5V rail. Ensure the supply stays above 4.38V during normal operation to avoid false resets.
