Digital Thermometer and Thermostat
DS1620
030598 1/12
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 non–
volatile
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

DESCRIPTION
The DS1620 Digital Thermometer and Thermostat pro-
vides 9–bit temperature readings which indicate the
temperature of the device. With three thermal alarm out-
puts, 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.
User–defined temperature settings are stored in non–
volatile memory, so parts can be programmed prior to
insertion in a system, as well as used in stand–alone
applications without a CPU. Temperature settings and
temperature readings are all communicated to/from the
DS1620 over a simple 3–wire interface.
