Hysteresis
To prevent output "chattering" at the trip point tempera-
ture, the temperature detector in the TC622/624 has 2
°
C of
hysteresis (See Figure 1).
The outputs are driven active when the temperature
crosses the setpoint determined by the external resistor. As
temperature declines below the setpoint, the hysteresis
action will hold the outputs true until the temperature drops
2
°
C below the threshold.
