Digital Temperature Sensor and Thermal Watchdog

The NXP PCT2075 is a temperature-to-digital converter having a power supply range from 2.7 V to 5.5 V.  It has a ± 1 ºC accuracy over – 25 ºC to + 100 ºC. The PCT2075 can be configured for different conditions from normal mode to periodically monitoring ambient temperature, or in shut-down mode to minimize power consumption.


Where Used?

  • System thermal management
  • Personal computers
  • Electronics equipment
  • Industrial controllers

Why Used?

  • Replaces LM75 series but allows up to 27 devices on the bus
  • Supply current of <1.0 μA in shut-down mode for power conservation
  • Stand-alone operation as thermostat at power-up
  • 1 MHz Fast-mode Plus 30 mA SDA drive allows more devices on the same bus but is backward compatible to Fast-mode and Standard-mode
  • 11-bit ADC that offers a temperature resolution of 0.125 °C
