Application Examples
Triac Control for up to 50 mA Gate Trigger Current
A phase control with a directly controlled triac is shown in the figure. The triggering angle of
the triac can be adjusted continuously between 0˚ and 180˚ with the aid of an external
potentiometer. During the positive half-wave of the line voltage, the triac receives a positive
gate pulse from the IC output pin 15. During the negative half-wave, it also receives a positive
trigger pulse from pin 14. The trigger pulse width is approx. 100 s.
