Vmains == Mains supply voltage When the potential on Pin 3 reaches the set point level of Vgmax = Maximum supply voltage Pin 4, a trigger pulse width, tp, is determined from the Tot = Total current consumption = Tsmax +1x value of Cg (tp = 9 ws/nF). At the same time, a latch is set Tsmax = Maximum current consumption oftheIC with the output pulse, as long as the automatic Ix = Current consumption of the retriggering has not been activated, then no more pulses external components can be generated in that half cycle. Control input at Pin 4 Viliaoe Wanton (with respect to Pin 10) has an active range from 8 8 Vgto—l V. When V4 = Vg, then the phase angle is at its As the voltage is built up, uncontrolled output pulses are maximum, O4max, 1.e., the current flow angle is minimum. avoided by internal voltage monitoring. Apart from that The minimum phase angle, Omin, is set with V4 = —1 V. all the latches in the circuit (phase control, load limit ewe tic Retri ‘ regulation) are reset and the soft-start capacitor is short MOIRA SELES eens circuited. This guarantees a specified start-up behavior The current-detector circuit monitors the state of the triac each time the supply voltage is switched on or after short after triggering by measuring the voltage drop at the triac interruptions of the mains supply.

b) Auto start (Pin 9 — open) ¢) Imax (V9 = Vg) The circuit behaves as written under Omax (V9 = 0), When Ve has attained the overload threshold with the exception that Pin 6 is not connected to maximum value i.e. Vg = Vrj090; Pin 13 is switched GND. If the value of Vg decreases to 25% of the to Pin 8 (Vpeg) through the resistance R (= 2 kQ) threshold value (V725), the circuit becomes active without soft-start capacitor discharging at Pin 7. again with soft-start. With this mode of operation, direct load current control (Imax) 1s possible. A recommended circuit is shown in figure 18.
