Description

General part information

DS1720 Series

The DS1720 Digital Thermometer and Thermostat provides 9-bit temperature readings which indicate the temperature of the device. With three thermal alarm outputs, the DS1720 can also act as a thermostat. THIGHis driven high if the DS1720's temperature is greater than or equal to a user-defined temperature TH. TLOWis driven high if the DS1720's temperature is less than or equal to a user-defined temperature TL. TCOMis driven high when the temperature exceeds THand 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.ApplicationsConsumer ProductsIndustrial SystemsThermally Sensitive SystemsThermometersThermostatic Controls
