DESCRIPTION

The DS1720 Digital Thermometer and Thermostat pro-

vides 9–bit temperature readings which indicate the

temperatureofthedevice. Withthreethermalalarmout-

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

DS1720 over a simple 3–wire interface.

puts, the DS1720 can also act as a thermostat. T

HIGH

driven high if the DS1720’s temperature is greater than

or equal to a user–defined temperature TH. T is

LOW

driven high if the DS1720’s temperature is less than or

equalto a user–defined temperature TL. T is driven
