- Converts Temperature to Digital Word in 750ms (max)
- Thermostatic Settings are User-Definable and Nonvolatile
- Can Be Used in a Wide Variety of Applications
- Supply Voltage Range Covers From 2.7V to 5.5V
- Data is Read From/Written Via a 3-Wire Serial Interface (CLK, DQ, Active-Low RST )
- Saves Space
- Requires No External Components
- 8-Pin DIP or SOIC (208-mil) Packages
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 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.
