... Microchip Technology Inc. 3.2 Hysteresis To prevent output “chattering” at the trip point tempera- ture, the temperature detector in the TC622/TC624 has 2°C hysteresis (see Figure 3-2). The outputs are driven active when the temperature crosses the set point , the OUT and determined by the external resistor. As temperature declines below the set point, the hysteresis action will hold the outputs true until the temperature drops 2° ...

The fan turns on when the sensed temperature rises above T temperature falls below T Figure 4-3 shows the TC622 acting as a heater thermostat. Circuit operation is identical to that of the cooling fan application ...
