TMP126DCKR

Temperature Sensors - Analog and Digital Output

digital temperature sensorSPI175°CSC70CRCthermal alert

TMP126DCKR is a high-temperature, factory-calibrated SPI temperature sensor for thermal monitoring and protection where a 6-pin SC70 package and up to 175°C operation are required.

Best for

  • High-temperature thermal monitoring
  • Programmable thermal protection
  • Low-power SPI sensor nodes

Avoid if

  • A standard four-wire SPI interface is required without an external isolation resistor
  • Negative temperature slew-rate detection is required
  • Operation above 175°C is required

Check before use

  • Verify thermal coupling between the sensor package and the monitored heat source.
  • Use a pull-up resistor for the open-drain ALERT output when ALERT signaling is needed.
  • Confirm the selected conversion period meets the datasheet accuracy condition.
