4_h_CONTROL_FOR_TRIAC

Published:2009/7/13 2:00:00 Author:May | From:SeekIC

Time at which triac is triggered by IC after momentarily pressing start switch is determined by resistor values used, When switch is released, charging capacitor C1 begins its long discharge interval. When voltage E1 becomes less than E2, pin 2 draws current and serves to reverse polarity of output at pin 6 for triggering triac. Diode limits maximum differential inputvoltage.-E. M.
