GENERAL DESCRIPTION
The DS620 digital thermometer and thermostat
provides low-voltage (1.7V d V
DD
d 3.5V) temperature
measurements with ?.5癈 accuracy from 0癈 to
+70癈 and an operating temperature range of -55癈
to +125癈. 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 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.
