TCN75-3.3 SOIC

I2C Temperature Sensor and Thermal Monitor
This is the 3,3V version. This means this sensor is optimized for a supply voltage of 3,3V. Nevertheless it has an operating supply voltage range of 2.7V to 5.5V

The TCN75 is a serially programmable temperature sensor that notifies the host controller when ambient temperature exceeds a user programmed set point. Hysteresis is also programmable. The INT/CMPTR output is programmable as either a simple comparator for thermostat operation or as a temperature event interrupt. Communication with the TCN75 is accomplished via a two-wire bus that is compatible with industry standard protocols. This permits reading the current temperature, programming the set point and hysteresis, and configuring the device.

  • Solid-State Temperature Sensing: 0.5°C Accuracy (Typ.)
  • Operates from -55°C to +125°C
  • Operating Supply Range: 2.7V to 5.5V
  • Programmable Trip Point and Hysteresis with Power-up Defaults
  • Standard 2-Wire Serial Interface
  • Thermal Event Alarm Output Functions as interrupt or Comparator/Thermostat Output
  • Up to 8 TCN75s may Share the Same Bus
  • Shutdown Mode for Low Standby Power Consumption
  • 5V Tolerant I/O at VDD = 3V
  • Low Power:
       - 250 μA (Typ.) Operating
       -1 μA (Typ.) Shutdown Mode
