DS1620+

DS1620+ is a digital thermometer and thermostat that 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 parts can be programmed prior to insertion in a system, as well as used in standalone applications without a CPU. Applications include thermostatic controls, industrial systems, consumer products, and thermometers.

• Simply adds temperature monitoring and control to any system
• Converts temperature to digital word in 750ms (max)
• Thermostatic settings are user-definable and non-volatile
• 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
• Thermometer error is ±0.5°C max at 0°C to +70°C, 3.0V ≤ VDD ≤ 5.5V
• Standby supply current is 1.5µA max at 0°C to +70°C
• 8-pin DIP package
• Measures temperatures from -55°C to +125°C
