RESET Timing Delay
The time delay for each supervisor can be adjusted by the capacitor at the CT1–CT4 pins. The EVM has
been configured with 0.1-µF capacitors on each of these pins for a nominal delay of 413.7 ms.

shows the operation of the RESET output with respect to the supervised voltage. The top trace shows
VCC1 as it ramps up from 0 V to 3.3 V and the bottom trace shows the delay before RESET1 goes high.
To change this delay, the following equations from the data sheet can be used to calculate a new timing
capacitor:
