Description

General part information

DS1620 Series

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. THIGHis driven high if the DS1620's temperature is greater than or equal to a user-defined temperature TH. TLOWis driven high if the DS1620's temperature is less than or equal to a user-defined temperature TL. TCOMis driven high when the temperature exceeds TH and stays high until the temperature falls below that of TL.User-defined temperature settings are stored in nonvolatile memory, so parts can be programmed prior to insertion in a system, as well as used in standalone applications without a CPU. Temperature settings and temperature readings are all communicated to/from the DS1620 over a simple 3-wire interface.ApplicationsConsumer ProductsIndustrial SystemsThermometersThermostatic Controls
