Temperature Switch ICs

Temperature Switch IC shifts its output from Low to High when the (selectable) detected temperature is reached and maintains a high output until the (selectable) hysteresis temperature is reached then the output switches to low. Detection temperature TDET can be selected in 1.0°C steps between the range of 60°C to 90°C.

Features
  • Detection temperature range: +60 °C~+90 °C
  • Low current consumption
  • High temperature accuracy: ±2.0 °C
  • Low power supply operation range: 1.6~5.0V
  • Wide operating temperature range
  • Hysteresis temperature 5°C steps
