The reset function provides several features:
Output Undervoltage Reset:
An output undervoltage condition is indicated by setting the Reset Output RO to “low”. This signal might be used
to reset a microcontroller during low supply voltage.
Power-On Reset Delay Time:
The power-on reset delay time
from exceeding the reset switching threshold
“low” to “high”. The power-on reset delay time
charged by the delay capacitor charge current
If the application needs a power-on reset delay time
capacitor’s value can be derived from the specified values in
with

•
For a precise calculation also take the delay capacitor’s tolerance into consideration.
