DS1620

Digital Thermometer and

Thermostat

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 750

ms (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.

THIGH is driven high if the DS1620’s temperature is greater than or equal to a user–defined temperature

TH. TLOW is driven high if the DS1620’s temperature is less than or equal to a user–defined temperature

TL. TCOM is driven high when the temperature exceeds TH and stays high until the temperature falls
