DESCRIPTION

The TK11052 is an accurate temperature controller IC for use over the -30 to +105 °C temperature range. The TK11052 monolithic bipolar integrated circuit contains a temperature sensor, stable voltage reference and two comparators, making the device very useful as an on/off thermostat. Two external resistors easily set the sensing temperature threshold and hysteresis of each thermostat. Its wide operating voltage range of 2.7 to 6.0 V makes this IC suitable for a number of applications requiring an accurate thermostat.

The TK11052 is available in a miniature SOT23L-8 surface mount package.
