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.
