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 TOS. 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.
