DS1775 - Digital Thermometer and Thermostat

Datasheet Summary

Description

The DS1775 digital thermometer and thermostat provides temperature readings that indicate the device’s temperature.

Thermostat settings and temperature readings are all communicated to/from the DS1775 over a simple 2-wire serial interface.

Features

  • Temperature Measurements Require No External Components.
  • Measures Temperatures from -55°C to +125°C (-67°F to +257°F).
  • ±2.0°C Thermometer Accuracy.
  • Thermometer Resolution is Configurable from 9 Bits to 12 Bits (0.5°C to 0.0625°C Resolution).
  • User-Definable Thermostat Settings.
  • Data is Read From/Written to Through a 2-Wire Serial Interface.
  • 2.7V to 5.5V Wide Power-Supply Range.
  • Software Compatible with DS75 2-Wire Thermal Wa.

GENERAL DESCRIPTION The DS1775 digital thermometer and thermostat provides temperature readings that indicate the device’s temperature. Thermostat settings and temperature readings are all communicated to/from the DS1775 over a simple 2-wire serial interface. No additional components are required; the device is truly a “temperature-todigital” converter. For applications that require greater temperature resolution, the user can adjust the readout resolution from 9 to 12 bits. This is particularly useful in applications where thermal runaway conditions must be detected quickly. The open-drain thermal alarm output, O.S., becomes active when the temperature of the device exceeds a user-defined temperature TOS. The number of consecutive faults required to set O.S.
