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.
