The TK11031 is a temperature sensor IC with a linear output of 10 mV/C over the range of -30 to + 105 C. Its wide operating voltage range of 4.5 to 10.0 V makes it suitable for a number of applications requiring accurate temperature control, such as electronic thermostats for climate control, refrigerators, and industrial process controls. The device is in the "on" state when the control pin is pulled to a logic high level.
