output is set to low. The reset delay capacitor provides a wide adjustment range for the
pulse repetition time. The watchdog function is only activated if the load exceeds 8 mA.
This ensures that a microcontroller is not activated during power-down and the current
drain is not increased. The IC is protected against overload and overtemperature.
