Configurable Timed Reset Using Discrete Logic

System controllers can use GPIO pins to reset other components if a fault is detected; however, system controllers generally cannot reset themselves or their entire system. By using a monostable multivibrator, the system controller can reset the entire system.

Either falling-edge or rising-edge trigger configurations can be used for this application. See the data sheet of your selected multivibrator for details
A pullup or pulldown resistor is required to return the input signal to a valid state once the system controller turns off. The recommended value for this resistor is 10 kΩ.
Retriggerable or non-retriggerable monostable multivibrators can be used for this operation
