NOTES: 1. Output pulses are centered with respect to zero crossing point. Pulse width is adjusted by the value of R
. Refer to application curves.

2. The actual sawtooth period depends on the AC power line frequency. It is exactly 2048 times the corresponding period. For the 50 Hz case it is 40.96
sec. For the 60 Hz case it is 34.13 sec. This is to comply with the European standard, namely that 2.0 kW loads cannot be connected or removed
from the line more than once every 30 sec.
3. 350 mV corresponds to 5°C temperature reduction. This is tested at probe using internal test pad. Smaller temperature reduction can be obtained by
adding an external resistor between Pin 4 and V . Refer to application curves.
CC
4. 350 mV corresponds to a hysteresis of 5°C. This is tested at probe using internal test pad. Smaller additional hysteresis can be obtained by adding
an external resistor between Pin 2 and V . Refer to application curves.
CC
5. Parameter guaranteed but not tested. Worst case 10 mV corresponds to 0.15°C shift on set point.
6. Measured at probe by internal test pad. 70 mV corresponds to 1°C. Note that the proportional band is independent of the NTC value.
7. At very low temperature the NTC resistor increases quickly. This can cause the sensor input voltage to reach the failsafe threshold, thus inhibiting
output pulses; refer to application schematics. The corresponding temperature is the limit at which the circuit works in the typical application. By
setting this threshold at 0.05 V , the NTC value can increase up to 20 times its nominal value, thus the application works below – 20°C.
