FEATURES
§
Requires no external components
§
Supply voltage range covers from 2.7V to
5.5V
§
Measures temperatures from -55°C to +125°C
in 0.5°C increments; Fahrenheit equivalent is
-67°F to +257°F in 0.9°F increments
§
Temperature is read as a 9-bit value
§
Converts temperature to digital word in 1
second (max)
§
Thermostatic settings are user-definable and
nonvolatile
§
Data is read from/written via a 3-wire serial
interface (CLK, DQ,
RST
)
§
Applications include thermostatic controls,
industrial systems, consumer products,
thermometers, or any thermally sensitive
system
§
8-pin DIP or SOIC (208-mil) packages

DESCRIPTION
The DS1620 Digital Thermometer and Thermostat provides 9–bit temperature readings which indicate
the temperature of the device. With three thermal alarm outputs, the DS1620 can also act as a thermostat.
T
HIGH
is driven high if the DS1620’s temperature is greater than or equal to a user–defined temperature
TH. T
LOW
is driven high if the DS1620’s temperature is less than or equal to a user–defined temperature
TL. T
COM
is driven high when the temperature exceeds TH and stays high until the temperature falls
below that of TL.
