FAQ
What is the purpose of the MIC94052YC6-TR reset timeout delay?
The reset timeout delay of approximately 140 milliseconds prevents the system from initiating a reset during brief voltage drops or transient disturbances. This ensures that the reset signal is only asserted when the supply voltage remains below the threshold for a sustained period, improving system stability and reducing unnecessary resets.
