Recommendations to the application circuit: The timer and the charge capacitors are loaded with an al-
ternating 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 maxi-
mum current during transients at each pin.
