Digital Thermometer and Thermostat
DS1625
030598 1/14
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)
Converts temperature to digital word in 500 ms (MAX)
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 DS1625 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.
*DS1621 WILL REPLACE DS1625
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
DS1625 over a simple 2–wire serial interface.
