Introduction –
Temperature Sensor ICs


ABLIC’s temperature sensor ICs offers digital output temperature sensor ICs that output a digital signal corresponding to the temperature, analog output temperature sensor ICs that output an analog voltage corresponding to the temperature, and temperature switch ICs (thermostat ICs) that output a H/L signal corresponding to the temperature.
We support the temperature monitoring and control of equipment with an extensive lineup of products featuring high accuracy, ultra-low current consumption and high temperature operation.

  1. ① Operation temperature range : -40℃~+125℃
  2. ② High-accuracy temperature detection : ±0.5℃ typ.
  3. ③ Built-in thermostat function

◆ Examples of Application Circuit

The temperature data detected in S-5852A can be digitally output to the MCU in high resolution 0.0625°C. Moreover, system resetting at a set temperature is also possible due to the thermostat function.

■ Major applications

LCD contrast compensation, device board temperature monitoring, etc.

・Other applications
 Information equipment, air conditioning systems, etc.

  1. ①Operation temperature range : -55℃~+130℃
  2. ② Excellent linearity
  3. ③ Simple circuit configuration : No need for parts such as resistors and operational amplifiers compared to thermistor configurations.

◆ Comparison between our analog output temperature sensor and a thermistor

■ Major applications

Image sensor temperature characteristic compensation, lithium-ion battery temperature monitoring, etc.

・Other applications
 Smartphone, smart speaker, etc.


3. Temperature Switch ICs

The output is inverted if the ambient temperature of the device reaches the IC’s set temperature.
Constant monitoring operation is available independent of microcontroller, realizing temperature protection and temperature management with a simple circuit configuration.
