The DS1621V+ is a digital thermometer and thermostat in 8 pin WSOIC package. It provides 9 bit temperature readings which indicate the temperature of the device. The thermal alarm output TOUT is active when the temperature of the device exceeds a user-defined temperature TH. The output remains active until the temperature drops below user defined temperature TL and allows for any hysteresis necessary. User-defined temperature settings are stored in non-volatile memory so parts may be programmed prior to insertion in a system. Temperature settings and temperature readings are all communicated to/from the DS1621 over a simple 2 wire serial interface.
Supply voltage range is 2.7V to 5.5V
Measures temperatures from -55°C to +125°C in 0.5°C increments (-67°F to +257°F in 0.9°F increments)
Temperature is read as a 9bit value
Converts temperature to digital word in less than 1s
Temperature measurements require no external components
