Recommendations to the application circuit: The timer and the charge capacitors are loaded
with an alternating current source. A short ground connection of the charge capacitor is
indispensable to avoid electromagnetic emigrations. The dimension of the resistors RD, RG
and RS have to respect the maximum current during transients at each pin.
