If you need to monitor heat sources in your application, our single- and multi-channel temperature sensor ICs have the features and flexibility to meet your specific design requirements.

Single-Channel Temperature Sensor Options

Also known as local channel digital temperature sensors, single-channel digital temperature sensors can be used in a variety of applications that require the measurement of local temperatures as an integral part of the system’s function and/or reliability. Available in I2C and SPI communication versions, our local channel digital temperature sensors feature flexible, user-programmable internal registers to configure the temperature sensor's performance and response to high and low temperature conditions. They also include dedicated alarm output activates if the temperature measurement exceeds the user-defined temperature and fault count limits.

  • Maximum temperature accuracy up to ±0.5°C

  • Operating voltages down to 1.7V

  • Low power consumption to optimize power savings

  • Available in ultra-small packages for space-constrained applications

  • Communications

  • Personal computers and servers

  • Consumer

  • Environmental

  • Medical devices

Analog Output Temperature Sensors

Analog output temperature sensors, also known as voltage output temperature sensors, feature low power consumption, good linearity and temperature accuracy as high as ± 0.5°C across the entire temperature operating range as wide as –40 to +125°C. These devices output voltages that interface well with an available stand-alone ADC or ADC channel in an MCU.  They are well suited for a variety of applications including automotive, home appliances, power regulators, portable equipment and battery packs.

  • Low operating current: 6µA typical

  • Extended temperature range: −40−C to +125−C

  • Available in 10 mV/−C and 19.5 mV/°C linear temperature slopes

  • Small packaging, including 3-pin SOT-23

Temperature Switches

Temperature switches, also known as logic output temperature sensors, simplify designs that require over and under temperature detection with their flexible factory-set trip points and pin-selectable hysteresis. Additional features include on/off logic control, low power consumption, small package sizes and ±0.5°C typical threshold temperature accuracy. They are excellent options for a number of applications including motor drives, RF power amplifiers, fan control and power supplies.

  • ±0.5°C typical threshold accuracy

  • Operating supply voltages from 2.7V to 18V

  • Dual trip points available on select devices

  • Small packaging options available including SOT-23

 

Multi-Channel Temperature Sensors

Multi-channel temperature sensors are used for monitoring and accurately measuring temperatures of multiple heat sources across distances of up to hundreds of feet. Also known as remote temperature sensors, these integrated devices are combined with inexpensive transistors to reduce costs, maintain accuracy and simplify monitoring of systems such as servers, networking and LCD projectors. They can also be connected to substrate diode pins and use beta compensation to measure temperatures on advanced processing devices such as CPUs, GPUs, FPGA and ASICs.

  • Up to eight channels of monitoring for BOM savings

  • Operating voltages down to 1.62V for 1.8V systems

  • Three-channel monitoring in 2 x 2 mm or five-channel monitoring in a 2 × 2.5 mm packages for space-constrained applications

  • Off-board or long trace capability for flexible design

  • Internet of Things (IoT)

  • Industrial

  • Computing, SSD and data centers

  • Portable electronics

  • Battery-operated devices

  • Appliances
