The DS620 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. The DS620 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.
The DS620 has thermostat functionality with userdefined 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.
