  1. 2008/12/12 TK11052 - THERMOSTAT IC
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.

FEATURES
*Internal Temperature Sensor, Voltage Reference and Two Comparators with
