Digital Thermometer and Thermostat
DS1621
030598 1/15
FEATURES
Temperature measurements require no external com-
ponents
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 (two byte trans-
fer)
Wide power supply range (2.7V to 5.5V)
Converts temperature to digital word in 1 second
Thermostatic settings are user definable and nonvol-
atile
Data is read from/written via a 2–wire serial interface
(open drain I/O lines)
Applications include thermostatic controls, industrial
systems, consumer products, thermometers, or any
thermal sensitive system.

DESCRIPTION
The DS1621 digital thermometer and thermostat pro-
vides 9–bit temperature readings which indicate the
temperature of the device. The thermal alarm output,
T
OUT,
is active when the temperature of the device
exceeds a user–defined temperature TH. The output
remains active until the temperature drops below user
defined temperature TL, allowing for any hysteresis
necessary.
User defined temperature settings are stored in non–
volatile memory, so parts may be programmed prior to
insertion in a system. Temperature settings, and tem-
perature readings are all communicated to/from the
DS1621 over a simple 2–wire serial interface.
