That threshold is set for a nominal 5V supply rail — it triggers before the rail falls out of spec for downstream logic, then holds reset for a minimum of 140ms after the voltage recovers.
The exposed pad is internally connected to ground; leaving it floating hurts thermal performance and can shift the threshold accuracy at elevated temperatures.
The reset timeout is a minimum of 140ms. After the monitored voltage rises above the 4.55V threshold, the reset output stays low for at least 140ms before releasing, giving the system power rails time to stabilise.
