The open-drain output can be pulled up to a different voltage than the monitored rail, useful in mixed-voltage systems.
It is also ROHS3 compliant, so it meets the current European and global restriction-of-hazardous-substances requirements without needing an exemption review.
The output is open drain (open collector) with active-low polarity. This allows the reset signal to be pulled up to a different voltage than the monitored supply, and multiple open-drain outputs can be wire-ORed together.
The reset timeout is a minimum of 150ms. After the supply voltage rises above the 3.3V threshold, the reset output remains asserted for at least 150ms to allow the system oscillator and core logic to stabilize before the processor starts.
It is active low. The reset output goes low when the monitored supply drops below the 3.3V threshold and stays low through the 150ms timeout period after recovery.
