DESCRIPTION
TK11052
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.

Note 1: This spec. is an error between a temp. to which the comparator reverses and a set temp. The resistance values of Ra, Rb, Rc, Rd can be
calculated as follows:
VREF x TSM x TC
Ra or Rc =
(0.4925 + TSET x TC) x ISH
VREF x TSH x TC
Rb or Rd =
(VREF - 0.4925 - TSET x TC) x ISH
Note 2: When VTEMP < INPUT1, OUTPUT1 > 2.8 V (CLH). When VTEMP > INPUT1, OUTPUT1 < 0.3 V (CLL).
When VTEMP < INPUT2, OUTPUT2 < 0.3 V (CLL). When VTEMP > INPUT2, OUTPUT2 > 2.8 V (CLH).

Thermostat IC Application
Example:
• WINDOW TYPE OUTPUT
The following application protects the circuit within the operating temperature range of 0 to 85 °C. When the temperature
is 0 °C or less, or 85 °C or more, the N channel Mos transistor is turned OFF.
When the temperature returns to between 5 and 80 °C by the hysteresis function, the N channel Mos transistor is turned
ON.

Comparator Output Level in the Hysteresis Area
When the power supply voltage is applied with the ambient temperature in the hysteresis area, the state of the comparator
output level is uncertain.
A capacitor is connected between Pin1 (Pin 2) to GND or Pin 4 to Pin 1 (Pin 2) to fix the comparator output level.

Noise Reduction
When the thermostat IC is operated in a noisy environment (e.g., motor, fan, etc.), the noise on the signal lines may exceed
the limits of the comparator hysteresis window. This results in erratic comparator output levels. This can be corrected by
adding 0.1 µF capacitors from Pin 1 to GND (or Pin 4), Pin 2 to GND (or Pin 4), and Pin 4 to GND as shown below. The
configuration is determined by the desired comparator output level during power-up in the hysteresis area as described
earlier.
