FUNCTIONAL
CMOS
amplifier (the first second stage Amp) amplifies signal. multiple adjust through resistance capacitance outside. amplificatory signal voltage higher than (Typ 1.8V) lower than (Typ 1.15V), Window Comparer outputs high level.
Pulse Width Detector detects Window Comparer's pulse width, high pulse width more than 768*TTb, this pulse effect, RELAY traic triggered. Otherwise, ignored. When availability signal detected, RELAY outputs high level, TRAIC outputs pulse, Counter starts count, availability signal appears, Counter restarts count. After 245760*TTci, RELAY TRIAC stop output. connect CDS, control RELAY keep level daytime. When power crosses zero line, Zero Cross Detector generates pulse, permits TRIAC triggered, after 32*TTb.
