The TK11051 monolithic bipolar integrated circuit contains a temperature sensor, stable voltage reference and a comparator, making the device very useful as an on/off temperature controller. Two external resistors easily set the sensing temperature threshold and hysteresis. Its wide operating voltage range of 2.7 to 6.0 V makes this IC suitable for a number of applications requiring accurate temperature control. The device is in the “on” state when the control pin is pulled to a logic high level. The TK11051 is available in a miniature SOT-23L-6 surface mount package.
