DESCRIPTION

The DS1775 SOT23-5 Digital Thermometer and Thermostat provides temperature readings which

indicate the temperature of the device. 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–to–digital” 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 T_OS. The number of consecutive faults required to set O.S. active is

configurable by the user. The device can also be configured in the interrupt or comparator mode, to

customize the method which clears the fault condition.

As a digital thermometer, the DS1775 is software compatible with the DS75 2–Wire Thermal Watchdog.

The DS1775 is assembled in a compact SOT23–5 package allowing for low–cost thermal

monitoring/control in space–constrained applications. The low thermal mass allows for time constants

previously only possible with thermistors.

Applications for the DS1775 include personal computers/servers/workstations, cellular telephones, office

equipment, or any thermally–sensitive system.
