It is composed of 2 devices : The Controller is optimized for law consumption and high security triggering of the triac. When Vas [| 1 8 | Vu connected to Vss, the mode input activates an additional option. If the main power drops from 220V to 110V, the triac control remains locked to Ose /In LU 2 / | Mode the 220V mode and avoids any high voltage spike when the voltage is restored to 220V. Osc / Out [| 3 6 | N.C. When connected to Vpp, the mode input desacti- vates this option. Voo 4 5 | Ve The TRIAG is specially designed for this applica- tion. An optimization between sensitivity and dy- namic parameters of the triac gate highly reduces the lasses of supply resistor and allows excellent immunity against disturbances.
