It is composed of 2 devices : n The Controller is optimized for low VSS 1 8 VM consumption and high security triggering of the triac. When connected to V , the mode input SS activates an additional option. If the main Osc / In 2 7 Mode power drops from 220V to 110V, the triac control remains locked to the 220V mode and avoids any high voltage spike when the voltage Osc / Out 3 6 N.C. is restored to 220V. When connected to V , the mode input DD desactivates this option. VDD 4 5 VG n The TRIAC is specially designed for this application. An optimization between sensitivity and dynamic parameters of the triac gate highly reduces the losses of supply resistor and allows excellent immunity against disturbances.
