SL441C Overview
Key Features
- s Balanced zero voltage point crossing detector, spike filter and pulse generator for reliable triggering of the triac
- s A period pulse generator and bistable which are arranged to provide symmetrical burst control and eliminate 1 / 2 wave firing
- s Thermistor malfunction may be sensed and power automatically removed
- s A supply voltage sensing circuit which inhibits firing pulses when the supply is inadequate to guarantee proper circuit operation
- This eliminates stressing of the triac at switch-on
