The DS620U+T&R is a low voltage, ±0.5°C accuracy digital thermometer and thermostat in 8 pin μSOP package. This digital thermometer and thermostat provides low voltage (1.7V <= VDD <= 3.5V) temperature measurements with ±0.5°C accuracy from 0°C to +70°C and an operating temperature range of -55°C to +125°C. It communicates over a 2-wire digital interface. For distributed sensing applications, it is multidroppable with three address pins that allow up to eight DS620s to operate on a single bus. It has thermostat functionality with user defined thresholds stored in EEPROM registers and it can be configured for standalone thermostat operation. The programmable output (PO) pin serves as the thermostat output and this pin can also be configured to function as an active low control for peripheral devices. It has user selectable resolution as 10bit, 11bit, 12bit or 13bit (0.5°C, 0.25°C, 0.125°C & 0.0625°C LSB weight, respectively).
