DS1620S+T&R

The DS1620S+T&R is a digital thermometer and thermostat in 8 pin WSOIC package. It 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 non-volatile memory, so it 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.

• Supply voltage range is 2.7V to 5.5V
