Supervisors FAQ

What is the reset output polarity for the XC6129C27J9R-G?

The reset output is active-low, meaning the output goes low when the monitored voltage drops below the threshold.

Does this device include a manual reset function?

No, the XC6129C27J9R-G does not feature a manual reset pin; it relies solely on voltage monitoring for reset generation.
