CIRCUIT FUNCTIONAL DESCRIPTION  
Power Supply (Pin 5 and Pin 7)  
case the level is set at 5°C. This configuration can be useful  
for low temperature inertia systems.  
The application uses a current source supplied by a single  
high voltage rectifier in series with a power dropping resistor.  
Sawtooth Generator  
An integrated shunt regulator delivers a V  
voltage of  
EE  
In order to comply with European norms, the ON/OFF  
period on the load must exceed 30 seconds. This is achieved  
by an internal digital sawtooth which performs the  
proportional regulation without any additional component.  
The sawtooth signal is added to the reference applied to the  
comparator negative input. Figure 2 shows the regulation  
improvement using the proportional band action.  
– 8.6 V with respect to Pin 7. The current used by the total  
regulating system can be shared in four functional blocks: IC  
supply, sensing bridge, triac gate firing pulses and zener  
current. The integrated zener, as in any shunt regulator,  
absorbs the excess supply current. The 50 Hz pulsed supply  
current is smoothed by the large value capacitor connected  
between Pins 5 and 7.  
Noise Immunity  
Temperature Sensing (Pin 3)  
The noisy environment requires good immunity. Both the  
voltage reference and the comparator hysteresis minimize  
the noise effect on the comparator input. In addition the  
effective triac triggering is enabled every 1/3 sec.  
The actual temperature is sensed by a negative  
temperature coefficient element connected in a resistor  
divider fashion. This two element network is connected  
between the ground terminal Pin 5 and the reference voltage  
– 5.5 V available on Pin 1. The resulting voltage, a function of  
the measured temperature, is applied to Pin 3 and internally  
compared to a control voltage whose value depends on  
several elements: Sawtooth, Temperature Reduction and  
Hysteresis Adjust. (Refer to Application Information.)  
Failsafe  
Output pulses are inhibited by the “failsafe” circuit if the  
comparator input voltage exceeds the specified threshold  
voltage. This would occur if the temperature sensor circuit is  
open.  
Temperature Reduction  
Sampling Full Wave Logic  
For energy saving, a remotely programmable temperature  
Two consecutive zero–crossing trigger pulses are  
generated at every positive mains half–cycle. This ensures  
that the number of delivered pulses is even in every case.

sync  
The pulse is centered on the zero–crossing mains waveform.  
Comparator  
When the positive input (Pin 3) receives a voltage greater  
than the internal reference value, the comparator allows the  
triggering logic to deliver pulses to the triac gate. To improve  
the noise immunity, the comparator has an adjustable
